Acceleration

• A measure of the change in velocity during a period of time

• A measure of the change in speed during a period of time

• A measure of the change in time during a certain distance

• A measure of the increase in speed during a period of time

Newton's 2nd Law

• Net force is equal to: mass times acceleration

• Net force is equal to: mass divided by acceleration

• Net force is equal to: speed times acceleration

• Net force is equal to: he who smelt it equals he is the one who dealt it

Net Force

• The sum of all the forces acting on an object

• The total amount of acceleration over a period of time

• The sum amount of the push and pull on an object

• The total distance of an object before calculating Displacement

Newtons 1st Law

• An object in motion will stay in motion, an object at rest will stay at rest

• An object in motion will stay in motion unless it is met with an equal force

• An object at rest will be in motion only after meeting another object already in motion

• Net force is equal to mass times acceleration

Free-body diagram

• A simple model to understand systems of objects with any amount of applied force

• A complex model to understand systems of objects traveling at any speed

• A simple model used to determine the velocity of an object without knowing its direction or speed

• A simple to use diagram on how to locate spare bodies for the purpose of building your own Frankenstein monster

Friction

• The force that resists the sliding motion of two surfaces that are touching

• The force that is required for two surfaces that are touching to move

• The only negative force applied when calculating Displacement

• The force that resists the sliding motion of two surfaces that proves Newtons 4th law
