When comparing the momentum of 2 moving objects, which of the following is correct?
the object with the higher velocity will have less momentum if the masses are equal
the more massive object will have less momentum if its velocity is greater.
the less massive object will have less momentum if the velocities are the same
the more massive object will have less momentum if the velocities are the same
a cannon recoils after shooting a cannon ball. the velocity of the cannon's recoil is small because the
impulse on the cannon is small
mass of the cannon is large
force on the cannon is small
mass of the cannon ball is large
Before the collision, mass 1 moves toward a stationary object (mass 2). The two objects with different masses collide. After the collision, mass 1 and mass 2 move in the same direction with different velocities. Identify the type of collision.
elastic
inelasatic
explosion
stationary
If the impulse acting on two objects is the same then
the mass of both objects is the same
the change in velocity of both objects is the same
the change in momentum of both objects is the same
the amount of contact time is the same
the force exerted on both objects is the same
Two skaters of different masses initially at rest push against each other so that they move in opposite directions. When they begin moving, which skater will have a greater velocity?
the smaller skater will have the greater velocity
the larger skater will have the greater velocity
they will have the same velocity
it is impossible to tell given the limited information
Which of the following has the largest momentum?
A fly buzzing across the room
A truck parked
A car driving down the road
Impulse is equal to change in
Velocity
Momentum
Kinetic energy
Force
How do crumple zones protect us?
They increase the force by increasing the contact time
They decrease the force by decreasing the contact time
They increase the force by decreasing the contact time
They decrease the force by increasing the contact time
A heavy object and a light object have the same momentum. Which has the greater speed?
Heavy object
Light object
Both have the same speed
What is the symbol used for momentum?
m
t
p
v
When two objects interact in an isolated system,
the momentum of each object is conserved
the total momentum of the system is zero
the total momentum is conserved only if the objects move in
opposite directions
the total momentum is always conserved
Two objects run into each other and stick together, traveling as one after the collision. What type of collision is this?
elastic
inelastic
explosion
none of the above
