Forces Flashcard 2/Gravity, Friction, Position, Motion

Front

What is gravity?

Back

Gravity is a force that pulls objects toward each other. It is what keeps us on the ground and causes objects to fall.

Front

What is friction?

Back

Friction is a force that opposes motion between two surfaces that are in contact. It can slow down or stop moving objects.

Front

What is a force?

Back

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

Front

What is motion?

Back

Motion is the change in position of an object over time. It can be described in terms of speed and direction.

Front

What is position?

Back

Position is the location of an object in relation to a reference point.

Front

What is an unbalanced force?

Back

An unbalanced force is when two forces acting on an object are not equal in size and direction, causing the object to move.

Front

What is a balanced force?

Back

A balanced force occurs when two forces acting on an object are equal in size and opposite in direction, resulting in no change in motion.

Front

What materials are attracted to magnets?

Back

Materials like iron, nickel, and cobalt are attracted to magnets, while wood, paper, and plastic are not.

Front

How does gravity affect objects on Earth?

Back

Gravity pulls objects toward the center of the Earth, giving them weight and causing them to fall when dropped.

Front

What is an example of friction in everyday life?

Back

An example of friction is when you rub your hands together to create warmth or when brakes are applied to stop a bicycle.
