Newtons Laws

Front

What is the unit of weight?

Back

Newton

Front

State Newton's First 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

Which law is best described by the concept of inertia?

Back

Newton's 1st Law

Front

Describe the scenario that illustrates Newton's 1st Law: A magician pulls a tablecloth out from under dishes and glasses on a table without disturbing them.

Back

This demonstrates inertia, where the dishes and glasses remain at rest due to their inertia.

Front

If a baseball player hits a ball with 400 N of force, how much force does the ball exert on the bat?

Back

400 N (According to Newton's 3rd Law: For every action, there is an equal and opposite reaction.)

Front

What is Newton's Second Law of Motion?

Back

F=ma (Force equals mass times acceleration.)

Front

What does the term 'inertia' refer to?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, calculated as weight = mass × gravitational acceleration.

Front

What is Newton's Third Law of Motion?

Back

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

Front

How does friction relate to Newton's laws?

Back

Friction is a force that opposes motion, affecting the net force acting on an object.
