5th Grade Force and Motion

Front

What is friction?

Back

Friction is a force that opposes the motion of an object. It occurs when two surfaces rub against each other.

Front

What is gravity?

Back

Gravity is a force that pulls objects toward each other, such as the force that pulls objects toward the Earth.

Front

What is a pull force?

Back

A pull force is a force that moves an object closer to another object.

Front

What is a push force?

Back

A push force is a force that moves an object away from another object.

Front

What happens to a skateboard when it goes down a hill?

Back

The skateboard accelerates due to gravity, but eventually stops due to friction.

Front

What is the role of mass in motion?

Back

Mass is the amount of matter in an object. Heavier objects require more force to move.

Front

What is the effect of gravity on a ball thrown in the air?

Back

Gravity pulls the ball back down to Earth after it is thrown.

Front

What is motion?

Back

Motion is the change in position of an object over time.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change an object's motion, while unbalanced forces cause an object to accelerate.

Front

What is an example of an unbalanced force?

Back

An example of an unbalanced force is when a person pushes a box, causing it to move.
