Momentum Impulse Theorem

Which statement is true about "Impulse-Momentum Theorem"?

• The greater the impulse exerted on something, the greater will be its change in momentum.

• The greater the impulse exerted on something, the lesser will be its change in momentum.

• The lesser the impulse exerted on something, the greater will be its change in momentum.

• Impulse is inversely proportional with momentum.

Kara Less was applying her makeup when she drove into South's busy parking lot last Friday morning. Unaware that Lisa Ford was stopped in her lane 30 feet ahead, Kara rear-ended Lisa's rented Taurus. Kara's 1300-kg car was moving at 11 m/s and stopped in 0.14 seconds. Determine the momentum change of Kara's car.

Explain the impulse-momentum theorem.

• The impulse-momentum theorem relates impulse to the change in momentum of an object.

• Impulse is equal to momentum.

• The theorem only applies to stationary objects.

• Momentum is independent of impulse.

How do you calculate impulse?

• Impulse = Energy × Time

• Impulse = Force × Time or Impulse = Change in Momentum

• Impulse = Mass × Velocity

• Impulse = Work × Distance

How does impulse relate to changes in momentum?

• Impulse is the same as force.

• Impulse decreases momentum.

• Momentum is independent of impulse.

• Impulse is equal to the change in momentum.
