Momentum and Impulse

How does mass affect momentum?

• An increase in mass results in an increase in momentum if velocity remains constant, as momentum is directly proportional to mass.

• Mass has no effect on momentum regardless of velocity.

• An increase in mass results in a decrease in momentum if velocity remains constant.

• Momentum is only affected by velocity, not mass.

If a car has a momentum of 2000 kg•m/s and its mass is 1000 kg, what is its velocity?

• 1 m/s

• 2 m/s

• 3 m/s

• 4 m/s

What is impulse?

• Impulse is the change in momentum of an object when a force is applied over a period of time, calculated as Impulse = Force × Time.

• Impulse is the total energy of an object in motion.

• Impulse is the force applied to an object divided by the time it takes to apply that force.

• Impulse is the mass of an object multiplied by its velocity.

What is the effect of doubling the mass of an object while keeping its velocity constant on its momentum?

• Doubling the mass will also double the momentum, as momentum is directly proportional to mass.

• Doubling the mass will have no effect on the momentum.

• Doubling the mass will halve the momentum.

• Doubling the mass will quadruple the momentum.

What happens to momentum in an elastic collision?

• Momentum is lost and kinetic energy is conserved.

• Both momentum and kinetic energy are conserved.

• Momentum is conserved but kinetic energy is lost.

• Momentum is gained and kinetic energy is conserved.

What is the formula for calculating total momentum before a collision?

• p_total = p1 + p2 + ... + pn

• p_total = m1 * v1 + m2 * v2

• p_total = F * t

• p_total = 1/2 * m * v^2

What is momentum?

• Momentum is the product of an object's mass and its velocity, represented by the formula p = mv.

• Momentum is the force applied to an object over time.

• Momentum is the energy of an object in motion.

• Momentum is the speed of an object in a given direction.

Calculate the momentum of a 5 kg object moving at 3 m/s.

• 10 kg•m/s

• 15 kg•m/s

• 20 kg•m/s

• 25 kg•m/s

If a bowling ball and a ping pong ball are moving at the same speed, which has more momentum?

• The bowling ball has more momentum because it has a greater mass.

• The ping pong ball has more momentum because it is lighter.

• Both have the same momentum since they are moving at the same speed.

• The bowling ball has less momentum because it is larger.

What is the effect of halving the velocity of an object on its momentum?

• Halving the velocity will double the momentum.

• Halving the velocity will have no effect on the momentum.

• Halving the velocity will also halve the momentum, as momentum is directly proportional to velocity.

• Halving the velocity will increase the momentum.
