Impulse and Momentum

What is the formula for impulse?

• Impulse = Force * Time

• Impulse = Work / Time

• Impulse = Distance / Time

• Impulse = Mass * Acceleration

Define momentum.

• Momentum is the force exerted by an object in motion.

• Momentum is the speed of an object.

• Momentum is the product of an object's mass and velocity.

• Momentum is the energy stored in an object.

How is impulse related to change in momentum?

• Impulse is less than the change in momentum

• Impulse has no relation to change in momentum

• Impulse is equal to the change in momentum

• Impulse is opposite to the change in momentum

State the law of conservation of momentum.

• Momentum can be created or destroyed in a closed system

• Total momentum of a closed system remains constant if no external forces are acting on it.

• Momentum is only conserved in open systems

• Momentum decreases with time in a closed system

Explain the difference between impulse and momentum.

• Impulse is the change in momentum over time, while momentum is the product of mass and velocity.

• Momentum is the change in impulse over time

• Impulse is the same as momentum

• Impulse is the product of mass and velocity

What are the SI units for impulse and momentum?

• m/s for impulse and kg for momentum

• kg for impulse and Ns for momentum

• Ns for impulse and m/s for momentum

• Ns for impulse and kg m/s for momentum

How does mass affect momentum?

• Mass has no effect on momentum

• Mass decreases momentum

• Mass increases momentum

• Mass affects momentum by directly influencing the momentum of an object.

Give an example of a real-life application of impulse and momentum.

• Baking a cake

• Watching a movie

• Car safety features like airbags

• Playing soccer

What is the principle behind airbags in cars?

• Manual inflation controlled by the driver

• Inflating based on the temperature inside the car

• Rapid inflation triggered by collision sensors

• Slow deflation triggered by collision sensors

Discuss the significance of impulse and momentum in sports.

• Impulse and momentum have no impact on sports performance

• Athletes can ignore impulse and momentum in their training

• Impulse and momentum only affect non-contact sports

• Impulse and momentum play a significant role in determining the outcome of collisions, the power of shots, and the overall performance of athletes in sports.
