Force and Motion

Front

What is force?

Back

A push or pull that can cause an object to move, change direction, or change speed.

Front

What is motion?

Back

The change in position of an object over time.

Front

What is the relationship between force and motion?

Back

Force causes motion; an object will not move unless a force is applied.

Front

What is gravity?

Back

A force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

Front

What happens to an object when a greater force is applied?

Back

The object will accelerate more than it would with a smaller force.

Front

What is inertia?

Back

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

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia, making it harder to change its motion.

Front

What is the effect of friction on motion?

Back

Friction opposes motion, slowing down or stopping moving objects.

Front

What is the role of a net force?

Back

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

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 unless acted upon by a net external force.
