• Motion

The change in an object's position over time relative to a reference point.

Frame of reference

A coordinate system or viewpoint used by an observer to specify the precise position, velocity, and behavior of objects in motion

Speed

The rate at which an object covers distance, calculated as distance divided by time.

Force

A push or a pull exerted on an object that can cause it to change its velocity (accelerate).

Matter

Anything that has mass and takes up space.

Energy

The ability to do work

Joules

What energy is measured in

Work

Force x distance

Kinetic energy

The energy an object possesses due to its motion

Potential energy

The stored energy an object possesses based on its position, state, or configuration relative to a reference point

• Acceleration due to gravity

• The steady acceleration experienced by an object in free fall within a vacuum, valued at approximately \(9.81\text{ m/s}^2\) near Earth's surface.

  
  

Law of conservation of energy

The foundational principle stating that total energy in an isolated system remains constant; it cannot be created or destroyed, only transformed from one form to another
