Why is it harder to push a van filled with bowling balls than it is to push a van with basketballs?
The mass of the car is greater than the mass of the basketballs
The mass of the bowling balls is greater than the mass of the basketballs
The van with the basketballs is bigger than the van with the bowling balls
It should be equally as hard to push the two vans
If the man pushes with an equal amount of force, which object will accelerate more?
Car because it has more mass
Lawnmower because it has less mass
Car because it has less mass
Lawnmower because it has more mass
The momentum of an object depends upon the object's ___________&_____________.
size and shape
mass and speed
mass and veloctiy
mass and energy
A 0.05 kg object rolling at 0.2 m/s.
A 0.15 kg object rolling at 2 m/s.

The impulse-momentum theorem states that
Athe impulse on an object is less than the change in momentum it causes
the impulse on an object is greater than the change in momentum it causes
the impulse on an object is equal to the change in momentum it causes
the force on a moving object is equal to the magnitude of the impulse.
The difference between a car hitting a wall vs. a car hitting a hay stack is
the change in momentum of the car hitting the wall is greater
the force on the car hitting the hay stack is greater
the Impulse on the car hitting the wall is greater
the collision time of the car hitting the hay stack is greater
If two objects have the same mass, then the faster moving object has ____________ momentum.
less
the same
more
None of these
Which takes more force to catch, a bowling ball or a ping pong ball?
bowling ball because it has more momentum
bowling ball because it has less momentum
both require the same amount of force when catching
ping pong ball because it has more momentum
A bicycle has a momentum of 24 kg•m/s. What momentum would the bicycle have if it had the twice the mass and was moving with twice the speed?
1/2 the momentum; 12 kg*m/s
4x the momentum; 96 kg*m/s
1/4 the momentum; 6 kg*m/s
twice the momentum; 48 kg*m/s
