Speed and Velocity

What is the formula to calculate speed?

• Speed = t ÷ d

• Speed = d x t

• Speed = d ÷ t

• Speed = t x d

What is speed?

• how far you go

• distance

  an object moves to the amount of time the object moves

• the change in the location of a object

• how fast you accelerate

What is necessary to describe motion accurately and completely?

• Velocity

• Displacement

• Frame of reference

• Speed

What is distance?

• length of a path between two points

• path of direction between two points

What is displacement?

• the length of the path between two points.

• the direction from the starting point and the length of a straight line from the starting point to the ending point.

What is the difference between average speed and instantaneous speed?

What is velocity?

• description of both speed and direction

  of motion

• description of speed

• description of direction

• description of motion
