Forces

Front

What is force?

Back

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

Front

What unit is force measured in?

Back

Force is measured in Newtons.

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 the opposing force, causing an object to move in the direction of the greater force.

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 friction?

Back

Friction is a force that opposes the motion of an object, caused by the contact between two surfaces.

Front

How does changing the height of a ramp affect the distance a toy car rolls?

Back

Increasing the height of the ramp generally increases the distance the toy car rolls due to greater gravitational potential energy.

Front

How does changing the surface of a ramp affect the distance a toy car rolls?

Back

Different surfaces create different amounts of friction, affecting how far the toy car can roll.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state.
