Forces and Motion

Front

What is force?

Back

A push or pull on an object that can cause it to move, stop, or change direction.

Front

What is motion?

Back

The change in position of an object over time.

Front

What is friction?

Back

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

Front

What is gravity?

Back

A force that pulls objects toward each other, such as the pull of the Earth on objects.

Front

What happens when you increase the force applied to an object?

Back

The object will accelerate and move faster.

Front

How does oil affect the movement of machine parts?

Back

Oil reduces friction, allowing the parts to move more easily and quickly.

Front

What is the relationship between force and motion?

Back

Force causes motion; without force, an object will not move.

Front

What is the unit of force?

Back

Newton (N) is the unit used to measure force.

Front

What is balanced force?

Back

When two forces acting on an object are equal in size but opposite in direction, resulting in no movement.

Front

What is unbalanced force?

Back

When two forces acting on an object are not equal, causing the object to move in the direction of the greater force.
