The meeting of particles or of bodies in which each exerts a force upon the other

Energy

The capacity to do work or produce change

it can exist in various forms such as kinetic

potential

Law of Conservation of Energy

A fundamental law stating that energy cannot be created or destroyed

Kinetic energy

The energy an object possesses due to its motion.

Potential energy

The stored energy an object has due to its position

Energy transfer

The movement of energy from one object

Sound energy

The energy carried by sound waves

Thermal (heat) energy

The internal energy of a system due to the kinetic energy of its particles

commonly experienced as heat.

Contact force

A force that acts between objects that are physically touching each other.

Non contact force

A force that acts between objects that are not in physical contact with each other.
Gravity A natural force of attraction that pulls objects toward each other

Newton (N)

The standard unit of force in the International System of Units (SI).

Balanced forces

Forces acting on an object that are equal in size and opposite in direction

Unbalanced forces Forces acting on an object that are unequal in size and/or not opposite in direction

causing a change in the object's motion.

Net force

The overall or total force acting on an object after all individual forces are combined.

Deformation

A change in the shape or size of an object due to an applied force.
