Impulse and Momentum

Question 1

An object which is moving at a constant speed has momentum.

Answer 1

TRUE

Question 2

Two objects of different masses are moving at the same speed; the more
massive object will have a greater momentum.

Answer 2

TRUE

Question 3

A less massive object can never have more momentum that a more
massive object.

Answer 3

FALSE

Question 4

Two different objects are moving at the same speed. The larger object
is more difficult to stop.

Answer 4

TRUE

Question 5

An object with varying speed will have varying momentum.

Answer 5

TRUE

Question 6

Objects involved in collisions encounter impulses.

Answer 6

TRUE

Question 7

Impulse is the force needed to produce a change in the body’s
momentum through a combination of changes in its mass and/or
velocity

Answer 7

TRUE

Question 8

In a collision, the impulse experienced by an object is not equal to its
momentum change.

Answer 8

FALSE

Question 9

Two cars with the same mass collided but they have different velocities.
Car B travels faster than Car A. Therefore, Car A has greater
momentum change than Car B.

Answer 9

FALSE

Question 10

Two objects collide. Object A has greater mass and velocity while
Object B has smaller mass and velocity. In this case, Object A has
greater change of momentum or impulse.

Answer 10

TRUE

Question 11

Momentum Formula

Answer 11

p=mv
