Two spheres are moving towards each other. When the spheres collide, their motion will change. A change in the motion of the spheres will occur because of which of the following?
The force of friction decreases.
Gravity is acting on the spheres.
The mass of the spheres stays the same.
Energy will be transferred between the spheres.
The total kinetic energy of two cars is measured before and after they crash into each other. The total kinetic energy of the two cars after the crash is less than the total kinetic energy before the crash. Which of the following best explains the loss of kinetic energy?
The car with more mass gave up its kinetic energy to the car with less mass.
Some of the cars' kinetic energy was converted to sound and heat energy.
Both of the cars were being pulled downward by the force of gravity.
Energy in a system is always lost.
Which of the following conditions is necessary in order to change the acceleration of an object?
Energy must move into or out of the object.
The friction acting on the object must be zero.
The total mass of the object must increase.
All forces acting on the object must be in balance.
