Force & Motion Evaluate SC.5.P.13.1, 13.2, 13.3, 13.4

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 does it mean for forces to be balanced?

Back

When two or more forces acting on an object are equal in size but opposite in direction, resulting in no change in motion.

Front

What happens to an object at rest when all forces acting on it are balanced?

Back

The object will stay still.

Front

What is gravity?

Back

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

Front

What is air resistance?

Back

A force that opposes the motion of an object through the air, slowing it down.

Front

How does a parachute work?

Back

It creates air resistance, which slows down the fall of a person or object.

Front

What is friction?

Back

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

Front

What happens when you push an object with more force?

Back

The object will accelerate and move farther.

Front

What is the relationship between mass and force?

Back

The greater the mass of an object, the more force is needed to change its motion.
