IMPULSE AND MOMENTUM G9

What is impulse in the context of vehicular collisions?

• Impulse is the weight of the vehicles in the collision

• Impulse in vehicular collisions is the product of force and time.

• Impulse is the speed of the vehicles involved in the collision

• Impulse is the distance traveled by the vehicles during the collision

Explain the concept of momentum conservation in collisions.

• The concept of momentum conservation in collisions is based on the principle that the total momentum of a closed system remains constant before and after the collision.

• Momentum conservation does not consider the direction of motion in collisions.

• Momentum is only conserved in elastic collisions, not inelastic collisions.

• Momentum conservation is only applicable to objects of equal mass.

How do you calculate the momentum before a collision?

• Momentum before collision = mass - velocity

• Momentum before collision = mass / velocity

• Momentum before collision = mass x velocity

• Momentum before collision = mass + velocity

Describe the process of calculating momentum after a collision.

• Ignore conservation of momentum

• Calculate initial momentum of each object, apply conservation of momentum, and solve for final momentum of objects.

• Calculate final momentum first

• Use kinetic energy instead of momentum

Define the relationship between impulse and momentum.

• Impulse is the same as momentum

• Impulse is the derivative of momentum

• Impulse and momentum are unrelated concepts

• The relationship between impulse and momentum is defined by the impulse-momentum theorem.

In a vehicular collision, how does impulse affect the outcome?

• Impulse has no impact on the outcome of a vehicular collision

• Impulse increases the safety of the passengers in the vehicles

• Impulse changes the momentum of the vehicles, affecting the outcome of the collision.

• Impulse causes the vehicles to move in the opposite direction

Why is it important to consider momentum conservation in collisions?

• To increase the total energy of the system

• To decrease the total momentum of the system

• To ignore the laws of physics

• To understand how the total momentum of a system is conserved before and after a collision.
