Systems of Particles & Linear Momentum
What is the impulse experienced by an object equal to?
The change in momentum of the object
The distance traveled by the object during the application of force
The force applied divided by time
The velocity of the object multiplied by its mass
How will an increase in temperature affect a perfectly elastic head-on collision between two identical metal spheres?
Both spheres will move faster after collision due to increased kinetic energy from higher temperatures.
Both spheres will have slower post-collision velocities since thermal expansion reduces their elasticity.
One sphere will experience an increase in post-collision speed, while the other slows down due to heat distribution asymmetry.
There will be no change in the post-collision velocities of each sphere compared to if they were at lower temperature.
A projectile launched horizontally from a height above the ground reaches terminal speed seconds later without experiencing air resistance. When it begins to fall freely downward, which parameter will experience the greatest increase upon reaching the ground?
Velocity vector
Potential energy
Angular acceleration
Kinematic energy
If a 0.5 kg ball moving with a speed of 3 m/s is brought to a stop by a net force over a distance of 2 m, what impulse was applied to the ball?
-3 kg·m/s
-0.75 kg·m/s
-1.5 kg·m/s
-6 kg·m/s
Which scenario would result in an object having zero final momentum after experiencing an external impulse?
An object at rest being struck head-on by another object with double its mass traveling at half its original speed.
An object at rest being struck by another object with equal mass traveling at equal speed but opposite direction.
An object moving northward being pushed northward by an external unbalanced force.
An object moving eastward struck from behind by another object with half its mass.
If a block of mass m is at rest on a frictionless surface and collides elastically with another block of half its mass that is moving at velocity v, what would be the final speed of the original stationary block after the collision?
(1/2)v

(2/3)v
(1/3)v

A block sliding on a frictionless surface collides with a spring attached to another block at rest; how does doubling both masses impact maximum compression of the spring?
Maximum compression doubles since both blocks have more mass, thus exerting more force on the spring during impact.
Maximum compression halves because although there's more mass, it requires more force for further compression which isn't provided just by increasing mass alone.
Maximum compression of the spring remains unchanged because it depends on system momentum and energy which are conserved quantities regardless of mass scaling.
Maximum compression varies inversely to the mass of the blocks; as mass doubles, compression decreases by half.
A block sliding on a horizontal surface reaches an edge and begins to fall; what is likely to happen to its linear momentum after it leaves contact with the surface?
It will be retained since there are no external forces acting in the direction of its initial motion.
It will increase because of gravity's pull in the downward direction.
It will become zero as the block is no longer on a solid foundation.
It will decrease due to air resistance.
When a force is applied to an object for a specific amount of time, which quantity directly measures the change in the object's momentum?
