Understanding Newton's Laws of Motion

Front

What is Newton's First Law of Motion?

Back

An object in motion stays in motion unless acted upon by an external force.

Front

Provide an example of Newton's First Law of Motion.

Back

A car coming to a stop at a red light.

Front

What is the formula for calculating force?

Back

Force = mass × acceleration (F = m × a).

Front

Calculate the acceleration of a 5 kg object when a net force of 20 N is applied to it.

Back

4 m/s².

Front

If a car has a mass of 1000 kg and accelerates at 2 m/s², what is the net force acting on it?

Back

2000 N.

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is the relationship between mass, acceleration, and force?

Back

Force equals mass times acceleration.

Front

Calculate the net force acting on a 20 kg object moving with an acceleration of 4 m/s².

Back

80 N.

Front

What is Newton's Third Law of Motion?

Back

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

Front

Give an example of Newton's Third Law of Motion.

Back

When you push against a wall, the wall pushes back with equal force.
