The SUVAT formulas – velocities

SUVAT, or simply the five equations of motion, represents a set of formulas crucial in physics for analyzing systems undergoing uniform acceleration. These equations, involving initial velocity (u), final velocity (v), and time taken (t), offer comprehensive insights into the kinematics of such systems.

In graphing velocity against time using u, v, and t, acceleration (a) becomes evident as the slope of the plotted line. Mathematically, acceleration (a) is expressed as the change in velocity (Δv) divided by the change in time (Δt). With initial and final velocities known (Δv = v – u) and assuming the graph starts at time = 0 (Δt = t), the acceleration formula simplifies to:

a= v−u/
t

​

This formula can be rearranged to yield the widely used expression:

v=u+at

The SUVAT formulas – displacement

Let’s delve into the SUVAT calculator, where “s” represents displacement – the distance covered by an object from its starting position during time “t.” It’s crucial to note that displacement differs from distance; if the object returns to its starting point, the displacement is zero. On our velocity-time graph, “s” corresponds to the area beneath the linear plot. This area is determined by multiplying the average velocity, expressed as (u + v) / 2, by the time taken, “t.” The formula for displacement is thus given by:

s= 1/
2

​
 (u+v)t.

For further equations, consider substituting v=u+at. This yields:

s= 1/
2

​
 (u+u+at)t,

which simplifies to:

s= 1/
2

​
 (2ut+at 
2
 ),

or alternatively:

s= 1/
2

​
 (2uv+ 1/
2

​
 at 
2
 ).

Another form can be obtained by using u=v−at:

s=vt− 1/
2

​
 at 
2
 .

Feel free to derive this last equation as an exercise! It involves similar steps as the previous derivation.

The SUVAT formulas – skipping time

Let’s tackle the last SUVAT formula, but don’t worry—it’s like a blast from the past when you were 14. If we make time (t) the subject of the first equation, we get:

t= v−u/
a

​

Now, if we substitute this into the second equation, we end up with:

s= 1
/
2
​
 a(u+v)( v−u/
a

​
 )

Simplify that by multiplying both sides by 2a, and we get:

2as=(u+v)(v−u)

Now comes the quadratic expansion part. After some effort, you’ll arrive at:

2as=v 
2
 −u 
2

Rearrange for v2, and you get:

v 
2
 =u

 +2as

What does SUVAT stand for?

You’ve likely caught on to the SUVAT calculator’s mechanics by now (unless you breezed through the technical details above). SUVAT stands for the key variables governing a system in motion with constant acceleration: displacement (s), initial velocity (u), final velocity (v), acceleration (a), and time (t). The arrangement of these letters might seem random, leading one to ponder why it’s not TUAVS, SAVUT, or USAVT. However, maintaining the proximity of initial and final velocity seems sensible, making ATUVS or STAUV perhaps more fitting options.

Components of SUVAT

Breaking down the acronym, each letter represents a key aspect of motion. S stands for displacement, indicating the change in position. U and V represent initial and final velocities, respectively. A signifies acceleration, the rate of change in velocity, and T is time, the duration of the motion. SUVAT Calculator

SUVAT Equations

At the core of SUVAT are four fundamental equations, each addressing a unique aspect of motion. These equations provide a mathematical framework for understanding and predicting an object’s movement. Let’s delve into each equation with illustrative examples. SUVAT Calculator

Equation 1: V=U+AT

This equation relates the final velocity (V), initial velocity (U), acceleration (A), and time (T). For instance, if a car starts from rest (=0U=0), and accelerates at 5 −25 ms−2 for 10 10 seconds, the final velocity (V) would be 50 −150 ms−1.

Equation 2: 2S=UT+21​AT2

This equation links displacement (S), initial velocity (U), acceleration (A), and time (T). It’s particularly useful for calculating the distance covered during accelerated motion.

Equation 3: V2=U2+2AS

A powerful equation connecting final velocity (V), initial velocity (U), acceleration (A), and displacement (S). It aids in situations where time might not be known.

Equation 4: 2S=2(U+V)T

This equation combines displacement (S), initial velocity (U), final velocity (V), and time (T). It’s handy for scenarios involving constant acceleration.

Real-world Applications

SUVAT isn’t confined to the theoretical realm; its applications extend to various real-world scenarios. Whether calculating the trajectory of a projectile, predicting the landing point of a free-falling object, or analyzing the motion of vehicles, SUVAT proves indispensable.

Consider a scenario where a ball is thrown vertically upwards (−1U=20 ms−1, −2A=−9.8 ms−2). Using SUVAT, we can determine the time of flight, maximum height reached, and the velocity at any given point during its ascent or descent. SUVAT Calculator

Understanding Acceleration

Acceleration, a core component of SUVAT, is often misunderstood. It doesn’t necessarily mean an increase in speed; it encompasses any change in velocity. A negative acceleration indicates deceleration or a decrease in speed. SUVAT allows us to grasp these nuances, fostering a deeper comprehension of motion. SUVAT Calculator

Speed and Velocity in SUVAT

In SUVAT, the distinction between speed and velocity is crucial. While speed is scalar, indicating only magnitude, velocity is a vector, incorporating both magnitude and direction.

SUVAT Calculator (FAQs)

How can I calculate acceleration without time?

To find acceleration when the time is unknown, you can follow these straightforward steps:

  1. Identify Initial and Final Velocities: Pinpoint the initial velocity (u) and final velocity (v) of the object in motion.
  2. Determine Displacement: Figure out the displacement (s) covered by the object.
  3. Apply the Formula: Use the formula for acceleration: a=v2−u2/2s​.
  4. Substitute Values: Insert the known values for u, v, and s into the formula to compute the result.

For instance, if the initial velocity (u) is 10 m/s, the final velocity (v) is 20 m/s, and the displacement (s) is 7.5 m, the acceleration can be calculated as follows:

​

Simplifying this expression yields an acceleration of 20 m/s².

How many SUVAT equations are there?

The SUVAT equations, representing fundamental principles of motion with constant acceleration, encapsulate five key variables:

  1. Displacement (s): The change in position of an object.
  2. Initial Velocity (u): The object’s speed at the starting point of motion.
  3. Final Velocity (v): The object’s speed at the endpoint of motion.
  4. Acceleration (a): The rate at which the object’s velocity changes.
  5. Time (t): The duration over which the motion occurs.

What are the SUVAT formulas?

Here’s the full list of all 5 SUVAT formulas:

  • Final velocity (v):
    v = u + at
  • Time (t):
    s = ½(u + v)t
  • Final velocity (v):
    v² = u² + 2as

These equations can be rearranged and combined as we like, to solve any physics problem involving a moving body.

What is the acceleration of a car moving with 25m/s velocity?

The equation v = u + at is one of the kinematic equations of motion, where:

  • v is the final velocity,
  • u is the initial velocity,
  • a is the acceleration, and
  • t is the time taken.

In this equation:
v = u + at

Each variable represents the following:

  • v (final velocity): The speed of the object at the end of the time period.
  • u (initial velocity): The speed of the object at the beginning of the time period.
  • a (acceleration): The rate at which the velocity is changing.
