Identify each statement as true or false. True False 1 2 Impulse is a measurement of the An impulsive force is constant over change in momentum of an object. time. Momentum is a vector quantity. Momentum and kinetic energy are always conserved in every collision. Exploration The momentum of an object depends on the of the object. mass velocity both mass and velocity None of the above The impulse is measured by finding the area under the force - time curve. True False The force experienced during an interaction can be reduced by increasing the of the interaction. time duration impulse momentum change All of the above

The momentum of each individual object in an isolated system is conserved. True False Elastic collisions are interactions during which the interacting objects stick together. True False Momentum is conserved in both elastic and inelastic collisions, while kinetic energy is conserved only in elastic collisions. True False Exercise 1 What would happen to the momentum of a marble in this experiment if the angle of the inclined ruler were increased or decreased? The greater the incline, the greater the momentum, while the smaller the incline, the smaller the momentum. This is because a marble going down a steeper incline will experience a greater acceleration due to gravity, thus increasing its velocity. Therefore, since momentum is mass times velocity increasing, its momentum will also increase.

nitial momentum is zero, while the marble(s) rolling down the ramp an initial momentum higher than zero. After the collision the momentum of the rollin ucing external forces and changing the momentum of the initially stationary marble. Based on your observations in Data Table 1, what can you conclude about the momentum of the released marble(s) just before the impact and the momentum of the marble(s) knocked away after the impact? Include how your observations support that momentum is conserved or not conserved in your answer.
