In which type of collision is total kinetic energy of the system conserved?
elastic collision
inelastic collision
If both the mass and velocity of an object are constant, what can you tell about its impulse?
Its impulse would be constant
Its impulse would be increasing
Its impulse would be decreasing
Its impulse would be zero
Two objects collide with each other and come to a rest.
How can you use the equation of conservation of momentum to describe this situation?
m1iv1i + m2iv2i = 0
m1iv1i − m2iv2i = 0
m1iv1i + m2iv2i = m1fv2f
Why does it hurt less when you fall on a softer surface?
The softer surface decreases the duration of the impact, thereby increasing the effect of the force.
The softer surface increases the duration of the impact, thereby reducing the effect of the force.
The softer surface increases the duration of the impact, thereby increasing the effect of the force.
The softer surface decreases the duration of the impact, thereby reducing the effect of the force.
Momentum is conserved in ....
an elastic collision of two balls
an inelastic collision of two balls
in the absence of an external force
in all of these examples
A rubber ball and a lump of clay have equal mass. They are thrown with equal speed against a wall. The ball bounces back with nearly the same speed with which it hit. The clay sticks to the wall. Which one of these objects experiences the greater momentum change?
The clay
The ball
Both of them experience the same non-zero momentum change
Both of them experience zero momentum change
Can a lighter object have more momentum than a heavier one?
No, because momentum is independent of the velocity of the object.
Yes, if the lighter object’s velocity is considerably low.
Yes, if the lighter object’s velocity is considerably high.
No, because momentum is independent of the mass of the object.
