Physics

Acceleration

• the change in velocity;speeding up, slowing down

Air Resistance

• the frictional force between air and objects

Balanced Forces

• forces are equal but in opposite directions

Force

• a push or pull;measured in Newtons

Friction

• a force that opposes motion between two touching objects

Gravitational Potential Energy

• energy an object posses because of its gravitational feild

Gravity

• an attractive force that exists between all objects

Inertia

• the tendency of an object to resist motion

Kinetic Energy

• energy in motion

Newton First Law of Motion (inertia)

• an object at rest tends to stay at rest an a object at motion tends to stay in motion until a unbalanced force acts on it

Newtons Second Law of Motion (f=mXa)

• it requires more force to move a larger mass

Newtons Third law of motion (action-reaction)

• for every action there is a equal and opposite reaction

Potential Energy

• energy an object has due to its position

Speed
