• 80m in total

• 0m

• Does he go 40m

• 0m in total

What does the p stand for in P=MV

• momentum

• mass

• velocity

• displacement

Motion

• The change in an objects position relative to its reference point.

• The distance and direction of the objects change in position.

• Units per second.

• p=mv

speed =

• Distance over time

• time over distance

• speed over time

• velocity

There were four guys on the right side of the rope and three on the left side of the rope playing tug of war . The right side pulled with the power of 90n and the left side pulled with the power of 60n. What kind of force is it (Balanced or unbalanced).

• balanced force

• normal force

• 30n to the right

• unbalanced force

How much mph are you going if you go 1500 miles in 30 hours?

• 50 mph

• 15 mph

• 50 m/s

Inertia

• A tendency for an object to resist a change in motion.

• The weight of an object

• the mass of an object

• The momentum of an object.

Law of conservation of momentum

• The total momentum of an isolated system remains constant.

• P=MV

• Conserving energy

• The total momentum does not remain constant.

• displacement

• friction

• force

• Motion
