This is an MCQ-based quiz on Force and Law of Motion.
This includes uniform, accelerated, and retarded motion
Among the equal-sized stone and a football, the inertia will be higher of:
What is the momentum of an object of mass m, moving with a velocity v?
When an object is released from a height, its initial velocity is:
A batsman hits a cricket ball which then rolls on the ground. After covering a short distance, the ball comes to rest. The ball slows to a stop because:
The batsman did not hit the ball hard enough.
Velocity is proportional to the force exerted on the ball.
There is a force on the ball opposing the motion.
There is no unbalanced force on the ball so the ball would want to come to rest.
Useful to us
Harmful to us
Both useful as well as harmful to us
None of them.
A goalkeeper in a game of football pulls his hands backwards after holding the ball shot at the goal. This enables the goalkeeper to
A passenger in a moving train tosses a coin which falls behind him. It means that motion of the train is
The inertia of an object tends to cause the object
To increase its speed
To decrease its speed
To resist any change in its state of motion
To decelerate due to friction
According to the third law of motion, action and reaction
Always act on the same body
Always act on different bodies in opposite directions
Have same magnitude and directions
Act on either body at normal to each other
An object of mass 2 kg is sliding with a constant velocity of 4 m/s on a friction less horizontal table. The force required to keep the object moving with the same velocity is:
Newton’s third law of motion explains the two forces namely ‘action’ and ‘reaction’ coming into action when the two bodies are in contact with each other. These two forces:
The speed of a car weighing 1500 kg increases from 36 km/h to 72 km/h uniformly. What will be the change in momentum of the car?

Inertia is the property of a body by virtue of which, it cannot change by itself
Which of the following is not an application of conservation of linear momentum?
The masses of two bodies are in ratio 5 : 6 and their velocities are in ratio 1 : 2. Then their linear momentum will be in the ratio
When we stop pedalling, the bicycle begins to slow down. This is because of the
Frictional force acting along the direction of motion of bicycle
Air resistance which is in the direction of motion
Frictional force acting opposite to the direction of motion of bicycle by the road
Nature of the bicycle to stop after some time
