What is meant by the term retardation? Name its S.I. unit.
A vehicle is accelerating on a straight road. Its velocity at any instant is 30 km/h. After 2 s, it is 33.6 km/h, and after further 2 s, it is 37.2 km/h. Find the acceleration of the vehicle in m s-2. Is the acceleration uniform?
From the velocity – time graph given below, calculate deceleration in region BC.
State if the following situation is possible:
A body moving with constant acceleration but with Zero velocity.
Sketch the shape of the velocity-time graph for a body moving with:
Uniform acceleration.
A car accelerates uniformly from a velocity of 18 km/h to 36 km/h in 15 min. What is its acceleration?
The slope of a velocity-time graph gives ______.
If the velocity of a body does not change, then its acceleration is ______.
Assertion: A positive acceleration of a body can be associated with the slowing down of the body.
Reason: Acceleration is a vector.
What is the difference between uniform acceleration and non–uniform acceleration?
