Newton's Laws

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 at a constant velocity unless acted upon by a net external force.

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 (F=ma).

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

Front

What is friction?

Back

Friction is the force that opposes the motion of an object when it comes into contact with another object.

Front

What is net force?

Back

Net force is the total force acting on an object after all the forces are combined.

Front

How does mass affect acceleration?

Back

The greater the mass of an object, the less acceleration it will have for a given force.

Front

What happens to a sled riding down a hill?

Back

The sled is accelerating due to the force of gravity acting on it.

Front

What is an example of Newton's First Law?

Back

A magician quickly pulls a tablecloth out from under dishes, and the dishes remain in place.
