Forces Calculations

What is velocity?

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

What is speed?

• how far you go
• how much distance is covered over a period of time
• how fast you accelerate
• the change in the location of a object

A runners races in the 100 meter dash.  It takes her 10 seconds to finish.  What is her average speed?

• 10 m/s
• 1000 m/s
• 100 seconds
• 10 seconds

If a force of 26 N is exerted on two balls, one with a mass of 0.52 kg and the other with a mass of 0.78 kg, which ball will have the greater acceleration?  (F=ma)

• The one with a mass of .78 kg will have the greatest acceleration.
• The one with a mass of .52 kg will have the greatest acceleration.
• They will both accelerate at the same rate.
