• Velocity

An object's change in position relative to a reference point

• Instantaneous Speed

• Velocity

• Distance

• Motion

How far an object has moved; measurement from one point to another.

The rate at which velocity changes over time.

• Speed

• Acceleration

• Distance

• Velocity

What is the difference between speed and velocity? 

• Velocity shows us how fast and object is going. Speed gives us speed and the direction of the object.

• There is no difference between velocity and speed.

• Speed shows us how fast and object is going. Velocity gives us speed and the direction of the object.

• Velocity is the distance travelled, and speed is the change in velocity.

Rate at which an object moves.

• Distance

• Velocity

• Acceleration

• Speed

What two things must you have to determine speed?

• velocity and time

• distance travelled and the time it takes to travel that distance

• displacement and speed

• temperature and wind speed
