Impulse & Momentum

What is the formula for impulse?

• Impulse = Work / Time

• Impulse = Mass * Acceleration

• Impulse = Force * Time

• Impulse = Distance / Time

State the Impulse-Momentum Theorem.

• Impulse = Mass x Acceleration

• Impulse-Momentum Theorem: Impulse = Change in Momentum

• Impulse = Force x Time

• Impulse = Velocity x Time

How is impulse related to momentum?

• Impulse is equal to momentum squared

• Impulse and momentum are completely unrelated concepts

• Impulse is related to momentum through the impulse-momentum theorem, where impulse is equal to the change in momentum.

• Impulse has no effect on momentum

Explain the concept of conservation of momentum.

• Momentum is conserved only in elastic collisions

• Momentum is conserved only in one-dimensional motion

• Momentum is conserved only when the objects are at rest

• The total momentum before a collision is equal to the total momentum after the collision.

How does the time of impact affect the impulse experienced by an object?

• The impulse experienced by an object increases as the time of impact decreases.

• The time of impact affects the impulse by changing the duration over which the force acts on the object.

• The time of impact has no effect on the impulse experienced by an object.

• The impulse experienced by an object decreases as the time of impact increases.

What are the units of impulse?

• Meters per second (m/s)

• Joules (J)

• Pascal (Pa)

• Newton-seconds (N*s) or kilogram-meters per second (kg*m/s)

Describe a real-life example where understanding impulse and momentum is crucial.

• Car safety during collisions

• Baking a cake

• Swimming in a pool

• Playing video games

How can impulse be calculated graphically?

• Find the slope of the force vs. time graph

• Calculate the area under the force vs. time graph

• Divide the force by the time

• Calculate the maximum force value

Discuss the significance of impulse in sports.

• Impulse in sports is irrelevant and does not impact performance.

• Impulse in sports is significant as it helps athletes generate power, change direction, and control their movements effectively.

• Impulse in sports only affects beginners, not professional athletes.

• Athletes should avoid using impulse as it leads to injuries.
