Force & Motion 5th Grade SOL Flashcard

Front

What is friction?

Back

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

Front

What is an example of helpful friction?

Back

An example of helpful friction is a bowling ball rolling down a lane, where friction helps it to roll smoothly.

Front

What is an example of harmful friction?

Back

An example of harmful friction is a person slipping on ice, where friction prevents movement and can cause falls.

Front

What is the relationship between force and motion?

Back

Force is a push or pull that can cause an object to move or change its motion.

Front

What does it mean for forces to be balanced?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What does it mean for forces to be unbalanced?

Back

Unbalanced forces are not equal, causing a change in motion, such as speeding up or slowing down.

Front

What requires the least amount of force to move?

Back

A giant balloon requires the least amount of force to move compared to heavier objects like a boulder or a car.

Front

What is a push or pull?

Back

A push or pull is a force applied to an object that can cause it to move or change direction.

Front

What happens to an object when a force is applied?

Back

When a force is applied to an object, it can start moving, stop moving, or change direction.

Front

What is an example of a force not being applied?

Back

A cat sleeping on the couch is an example of no force being applied, as it is not pushing or pulling anything.
