Force & Motion (5th Grade)

Front

What is gravity?

Back

Gravity is a force that pulls objects toward each other, such as the force that pulls a book to the ground.

Front

What is friction?

Back

Friction is a force that opposes motion between two surfaces that are in contact, slowing down movement.

Front

What is mass?

Back

Mass is the amount of matter in an object, which affects how much gravity acts on it.

Front

What is speed?

Back

Speed is the distance an object travels in a certain amount of time, calculated as distance/time.

Front

What is motion?

Back

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

Front

What is a force?

Back

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

Front

What is air pressure?

Back

Air pressure is the force exerted by the weight of air above an object, which can affect how objects move through the air.

Front

What happens when two forces act in opposite directions?

Back

When two forces act in opposite directions, they can cancel each other out or result in a net force that determines the object's motion.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity, which can occur when an object speeds up, slows down, or changes direction.

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, representing how much motion an object has.
