Acceleration - Some Basic Questions

What is acceleration?

• The rate of change of velocity

• The rate of change of displacement

• The rate of change of time

What is the formula for acceleration?

• a = v + u + t

• a = u - v / t

• a = v x u / t

• a = v - u / t

What is an example of non-uniform acceleration?

• A car driving at a constant velocity

• A ball rolling down a frictionless surface

• A bird flying in the sky

What is negative acceleration called?

• Acceleration

• Deceleration

• Non-uniform acceleration

What is the unit of acceleration?

• m

• m/s

• ms²

• m/s²

What is uniform acceleration?

• When an object's velocity changes at a constant rate

• When an object's velocity changes at a non-constant rate

• When an object's velocity remains constant

An object moves with an initial velocity (u) of 6 m/s and final velocity (v) of 3 m/s. This is an an example of:

• Negative Velocity

• Positive Acceleration

• Zero Acceleration

• Negative Acceleration

An object changes its 'u' of 5 m/s to 'v' of 8 m/s in 2 s. Calculate its acceleration?

• 1.5 ms

• 1.5 ms²

• 1.5 m/s²

• 6.5 m/s²

Which of the following can be a representation of non-uniform acceleration on an acceleration-time graph?

• A straight line

• A horizontal line

• A vertical line

• A curved line

This graph is an example of:

• Uniform velocity

• Uniform acceleration

• Non-uniform velocity

• Non-uniform acceleration
