MOMENTUM

What is the definition of momentum in physics?

• The force resulting from a moving object's mass and velocity
• The rate of increase of velocity of an object
• The rate at which an object's position changes
• The resistance of an object to a change in motion

What equation is used to calculate momentum?

• v = f/m
• F = ma
• mv = p
• p = mv

What is the momentum of an object with a mass of 10kg and a velocity of 5m/s?

• 10
• 50
• 25
• 2

What is the unit of momentum?

• N/s
• m/s
• N/m
• kg/m

What is the direction of momentum?

• In the same direction as the applied force
• In the direction of the object's motion
• In both directions
• It has no direction

What is the law of conservation of momentum?

• The total momentum of a system remains constant
• The total force of a system remains constant
• The total mass of a system remains constant
• The total velocity of a system remains constant

What is the formula for calculating impulse?

• F = mv
• v = F/m
• I = mv
• I = F∆t

What is the formula for calculating change in momentum?

• F = mv
• v = F/m
• p = mv
• p = F∆t

If two objects have the same momentum, what is true about their kinetic energies?

• Their kinetic energies are the same
• Their kinetic energies are different
• Their kinetic energies cannot be determined
• Their kinetic energies are unrelated
