Momentum and Impulse_SC

The momentum of an object depends upon the object's ___________&_____________.

• size and shape

• mass and speed

• mass and veloctiy

• mass and energy

Which one of the following units represents the standard metric units of momentum

• Newtons * meter / second

• Kilograms * meter / second²

• meter / second

• Kilograms * meter / second

Which one of the following units represents the standard metric units of impulse

• Kilograms * meter / second²

• Newton * meter

• meter / second²

• Newton * second

The law of conservation of momentum states that, 

• p before is less than p after
• p before is the same as p after
• p before is more than p after

When the speed of an object is doubled, its momentum

• remains unchanged in accord with the conservation of momentum.
• doubles
• quadruples
• decreases

An object that has momentum can be described as _________

• a) changing its velocity

• b) moving fast

• c) resisting changes in its state of motion

• d) having its mass in motion

• e) encountering a net force

Softer landings tend to

• increase impact force
• increase force
• increase collision time
• increase change in momentum

In any collision (crash) the ______ is ALWAYS constant.

• Total Momentum
• total speed
• total Velocity
• Energy

Which takes more force  to catch, a bowling ball or a ping pong ball?

• bowling ball because it has more momentum
• ping pong ball because it has more momentum
• both require the same amount of force when catching
• bowling ball because it has less momentum

Which one of these objects has the greater amount of momentum?

• A turtle that slowly crosses a road

• A parked car

• A stop sign
