Newton's Laws of Motion

Front

What is Newton's First Law of Motion?

Back

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.

Front

What is the formula for calculating force according to Newton's Second Law of Motion?

Back

Force = Mass × Acceleration.

Front

What does Newton's Third Law of Motion state?

Back

For every action, there is an equal and opposite reaction.

Front

What is the unit of force in the International System of Units (SI)?

Back

Newton (N).

Front

If a 10 kg object is accelerating at 5 m/s², what is the net force acting on it?

Back

50 Newtons.

Front

What is friction?

Back

A force that opposes the motion of an object.

Front

What is the acceleration of an object if a net force of 20 N is applied to a mass of 4 kg?

Back

5 m/s².

Front

What is weight?

Back

The force of gravity acting on an object, calculated as Weight = Mass × Gravity.

Front

What is the acceleration due to gravity on Earth?

Back

Approximately 9.81 m/s².

Front

What happens to the net force on an object when all forces acting on it are balanced?

Back

The net force is zero.
