Identifying Newton's Laws

Front

What is the definition of 'weight'?

Back

The force in which gravity pulls on an object.

Front

What is Newton's 1st Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is Newton's 2nd 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 (F=ma).

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

How does weight differ from mass?

Back

Weight is the force of gravity on an object, while mass is the amount of matter in an object.

Front

What is an example of Newton's 1st Law in everyday life?

Back

A book resting on a table will remain at rest until someone pushes it.

Front

How can you calculate force using Newton's 2nd Law?

Back

Force can be calculated using the formula F=ma, where F is force, m is mass, and a is acceleration.

Front

What is an example of Newton's 3rd Law?

Back

When you jump off a small boat, you push the boat backward as you move forward.

Front

What happens to an object in motion if no external forces act on it?

Back

It will continue to move at a constant velocity.

Front

What is the relationship between mass and weight?

Back

Weight is the product of mass and the acceleration due to gravity (W=mg).
