Newtons 1st Law: Force and Motion

Front

What is Newton's First Law of Motion?

Back

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

Front

What is inertia?

Back

The ability of an object to resist a change in its motion.

Front

What is acceleration?

Back

The rate of change of velocity of an object.

Front

What is the force that pulls objects towards each other?

Back

Gravity.

Front

What is speed?

Back

The measure of how fast an object is moving.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is friction?

Back

The force that opposes the motion of an object.

Front

What is a net force?

Back

The overall force acting on an object when all the individual forces are combined.

Front

What happens to an object in motion if no net force acts on it?

Back

It continues to move at a constant velocity.

Front

What is the relationship between mass and inertia?

Back

The greater the mass of an object, the greater its inertia.
