Class 11 Physics: Laws of Motion Worksheet

Which of Newton's laws of motion states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force?

The product of an object's mass and its velocity is defined as its ________.

A force of 10 N acts on an object of mass 2 kg. What is the acceleration produced?

Explain why it is difficult to walk on a slippery surface.

Which of the following is NOT a unit of force?

According to Newton's third law of motion, for every action, there is an equal and ________ reaction.

An object of mass 'm' is moving with velocity 'v'. If a force 'F' is applied to it, its momentum changes. According to Newton's second law, the rate of change of momentum is directly proportional to the applied force, and takes place in the direction of the force. This can be mathematically represented as:

Why do passengers tend to fall forward when a moving bus suddenly brakes?

Greater the mass of an object, greater is its ________.

The principle of conservation of linear momentum states that if no external force acts on a system of particles, then the total linear momentum of the system remains:
