Front

What is a force?

Back

A force is a push or pull that can change the motion of an object.

Front

What is gravity?

Back

Gravity is the force that pulls everything towards the Earth.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when one force is greater than another, causing an object to move in the direction of the greater force.

Front

What is acceleration?

Back

Acceleration is the rate at which an object speeds up or slows down.

Front

What is inertia?

Back

Inertia is the tendency of an object to stay at rest or in motion unless acted upon by an external force.

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 speed?

Back

Speed is the distance an object travels per unit of time.

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction.

Front

What is a balanced force?

Back

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

Front

What is the relationship between mass and force?

Back

The greater the mass of an object, the more force is needed to change its motion.
