◉ If work was done on an object, the object must have Answer: changed
its position.
◉ A brick slides across a horizontal rough surface and eventually comes
to a stop. What happened to the kinetic energy of the brick? Answer: It
was converted to other energy forms, mostly heat.
◉ What is possessed by a moving object, but not a stationary object?
Answer: Kinetic Energy
◉ The power of an engine is a measure of Answer: the rate at which it
can perform work.
◉ Which has the greater kinetic energy - a 1 ton car moving at 30 m/s or
a half-ton car moving at 60 m/s? Answer: The half-ton car.
◉ A 20 N ball and a 40 N ball are dropped at the same time from a
height of 10 meters. Air resistance is negligible. What is accurate?
Answer: Balls hit the ground at the same time but gravity does more
work on the heavy ball than on the light ball.
, ◉ When work is done by a force on an object, then what is true?
Answer: The work done is equal to the change of total energy of the
object plus any energy appearing as heat, light, or sound.
◉ A block sits on a slight incline, held at rest by the frictional force
between the block and the incline. What is true about this? Answer: The
work done by the frictional force is equal to the gravitational potential
energy of the block.
◉ A Teflon-coated box of rocks slides down a rough incline. What is
true about this? Answer: The mechanical energy of the block is
decreasing.
◉ Initially, a blue automobile has twice the kinetic energy that a red
automobile has. both are braked to a stop; both have the same amount of
braking force. The red auto will stop in _____________ as the blue auto.
Answer: four times the distance
◉ A mass hangs from a spring that is fixed to the ceiling. The mass is
now pulled down and released so the mass oscillates up and down.
Which of the following statements is true?
A. The kinetic energy of the oscillating mass is a constant.
B. Adding mass to the spring will make it oscillate faster.
C. The restoring force of the spring is equal to the weight of the mass.
