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 are the two main types of forces?

Back

The two main types of forces are contact forces and non-contact forces.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion.

Front

What is potential energy?

Back

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

Front

What is the difference between push and pull?

Back

A push moves an object away from you, while a pull brings an object closer to you.

Front

What is friction?

Back

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

Front

What is gravity?

Back

Gravity is a non-contact force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

Front

What is the formula for calculating kinetic energy?

Back

The formula for kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the role of forces in motion?

Back

Forces cause changes in the motion of objects, including starting, stopping, and changing direction.

Front

What is Newton's First Law of Motion?

Back

Newton's First Law states that an object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity unless acted upon by a net external force.
