Momentum and Collision

Question 1

is defined as the product of
the mass and the velocity

Answer 1

Momentum

Question 2

In order to change the momentum of an object,
a force must be applied

Answer 2

Impulse

Question 3

be the result of physical contact
between two objects

Answer 3

Collision

Question 4

may also arise from the electrostatic
interactions of the electrons in the surface atoms
of the bodies

Answer 4

Contact

Question 5

when no external forces act on a system consisting of
two objects that collide with each other, the total
momentum of the system remains constant in time

Answer 5

Principle of Conservation of Momentum

Question 6

momentum is conserved but kinetic energy is not

Answer 6

Inelastic Collision

Question 7

➢ Both momentum and kinetic energy are
conserved

Answer 7

Elastic Collision

Question 8

momentum is
conserved, kinetic energy is not, and the two
objects stick together after the collision, so their
final velocities are the same

Answer 8

Perfectly Inelastic Collision
