Give a scientific reason.
When an object falls freely to the ground, its acceleration is uniform.
An object of mass 16 kg is moving with an acceleration of 3 m/s2. Calculate the applied force. If the same force is applied to an object of mass 24 kg, how much will be the acceleration?
Give an example of an accelerated body, moving with a uniform speed.
Is it possible for an accelerating body to have constant speed?
Sketch the shape of the velocity-time graph for a body moving with:
Uniform acceleration.
A car starts from rest and it is travelling with a velocity of 20 m/s in 10 s. What is its acceleration?
Assertion: The accelerated motion of an object may be due to change in magnitude of velocity or direction or both of them.
Reason: Acceleration can be produced only by change in magnitude of the velocity. It does not depend the direction.
If the velocity of a body does not change, then its acceleration is ______.
The Unit of acceleration is ______.
Assertion: When a body is subjected to a uniform acceleration, it is always moving in a straight line.
Reason: Motion may be straight-line motion or circular motion.
