What is speed?

• a push or pull

• The tendacy of an object to resist changes in its motion

• Force that opposes motion, it occurs when things slide/roll over each other

• The rate at which the position of an object change

What is Velocity?

• The tendacy of an object to resist change in its motion

• Speed and Direction in which an object is moving

• Mass and Acceleration

• The force of attraction between any two objects that have mass

What is acceleration?

• The rate of change in velocity

• Same thing as speed

• How fast a object can slow down

• Acceleration isn't something we have learned
