Negative acceleration

• speed is increasing

• speed is decreasing

Acceleration

• The rate of change of position

• The rate of change of velocity

• Total distance traveled

Reference point

• is determined by the finish line

• the point use to determine if an object has moved

• the speed at which an object is moving

What does a speedometer show

• constant speed

• acceleration

• instantanous speed

Constant speed is

• Speed that does not vary and stays the same

• Speed at that exact moment

• Acceleration

What does a distance-time graph show?

• the rate of change of the acceleration of an object

• The distance an object travels over a period of time

What is the difference between speed and velocity

• speed is acceleration/ time and velocity is speed/time and direction

• velocity is distance/ time and speed is displacement/time and direction

• Speed is distance/ time and velocity is displacement/time and direction

Motion can be described as

• A change in velocity

• A change in speed

• A change in position
