Chapter 2 : Kinematics of linear motion

What is the formula to calculate speed?

• v = time / displacement

• v = displacement / time

• v = displacement x time

• v = time x displacement

What is velocity?

• the quickness of an object
• the location of an object
• acceleration
• speed in a specific direction
