momentum and impulse

WHICH OF THE FOLLOWING IS A UNIT OF MOMENTUM?

• kg.m^2/s

• kg/s

• m/s

• kg.m/s

WHAT DOES MOMENTUM DEPEND ON?

• Mass only

• Velocity only

• Neither mass nor velocity

• Both mass and velocity

HOW DOES MOMENTUM CHANGE DURING A COLLISION?

• It remains constant

• It increases

• It decreases

• It depends on the type of collision

WHICH OF THE FOLLOWING BEST DESCRIBES AN ELASTIC COLLISION?

• Only momentum is conserved

• Both momentum and kinetic energy are lost

• Kinetic energy is conserved

• Momentum is not conserved

WHICH OF THE FOLLOWING BEST DESCRIBES AN INELASTIC COLLISION?

• Momentum is conserved, but kinetic energy is not

• Both momentum and kinetic energy are conserved

• Only kinetic energy is conserved

• Neither momentum nor kinetic energy is conserved
