Forces and Motion

Front

What are balanced forces?

Back

Balanced forces are two or more forces acting on an object in opposite directions, causing the object to remain at rest or move at a constant speed.

Front

What are unbalanced forces?

Back

Unbalanced forces occur when two or more forces acting on an object are not equal in size or direction, causing the object to accelerate or change its motion.

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 friction?

Back

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

Front

What is magnetism?

Back

Magnetism is a force that can attract or repel certain materials, such as iron, and is produced by magnets.

Front

What happens when like poles of magnets are brought together?

Back

Like poles of magnets (north-north or south-south) repel each other.

Front

What happens when opposite poles of magnets are brought together?

Back

Opposite poles of magnets (north-south) attract each other.

Front

How does mass affect motion?

Back

An object with less mass will move farther than an object with more mass when pushed with the same force.

Front

What is the role of gravity in motion?

Back

Gravity pulls objects downward, influencing their motion, such as a ball rolling down a hill.

Front

What is a force?

Back

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