- Q1Which of the following statements best describes momentum?Momentum is always conserved in an isolated system.Momentum is the product of an object's mass and its velocity.Momentum is equal to force multiplied by time.Momentum is a measure of an object's energy.30s
- Q2If a 2 kg object is moving at a velocity of 3 m/s, what is its momentum?5 kg·m/s3 kg·m/s2 kg·m/s6 kg·m/s30s
- Q3In a collision between two objects, what property of momentum is conserved?Mass is conservedKinetic energy is always conservedVelocity of both objects is conservedTotal momentum of the system is conserved30s
- Q4Which of the following scenarios demonstrates the principle of conservation of momentum?A ball thrown vertically in the air.A person jumping off a diving board.A car accelerating down a hill.Two ice skaters push off each other and move in opposite directions.30s
- Q5What happens to the momentum of an object if its velocity is doubled while its mass remains constant?The momentum becomes zero.The momentum is also doubled.The momentum is halved.The momentum remains the same.30s
- Q6Which of the following best defines impulse?Impulse is the change in momentum of an object.Impulse is the mass of an object multiplied by its speed.Impulse is the rate of change of velocity.Impulse is the force applied over time.30s
- Q7In a closed system, if one object collides elastically with another object, what is true about their total momentum?Total momentum is doubled after the collision.Total momentum is lost during the collision.Total momentum is independent of the masses involved.Total momentum before the collision equals total momentum after the collision.30s
- Q8What is the unit of momentum in the International System of Units (SI)?NewtonKilogramJoulekg·m/s30s
- Q9What is the formula for calculating momentum?p = mv^2p = mvp = m + vp = m/v30s
- Q10Which of the following scenarios describes a change in momentum?A bicycle coasts down a hill without pedaling.A parked car remains stationary.A ball rolls at a constant speed.A car speeds up as it accelerates.30s
- Q11In an elastic collision, what happens to the total momentum of the system?It increases.It becomes zero.It decreases.It is conserved.30s
- Q12What does impulse measure in physics?Energy transferredChange in momentumForce over timeVelocity of an object30s
