Side A ------ Side B
If you push an object twice as far while applying the same force, you do ------ twice as much work
A job is done slowly, while an identical job is done quickly.  Both jobs require the same amount of work, but different amounts of ------ power
If an object is raised twice as high, its potential energy will be ------ twice as much
A ball rolling down an incline has its maximum kinetic energy at ------ the bottom
No work is done by gravity on a bowling ball that rolls along a bowling alley becauuse ------ the force on the ball is at right angles to the ball's motion
A jack system will increase the potential energy of a heavy load by 1000 J with a work input of 2000 J.  The efficiency of the jack system is ------ 50%
A moving object  has ------ speed, velocity, momentum, and energy
A feather and a coin dropped in a vacuum fall with equal ------ accelerations
Which moves faster in m/s on a merry-go-round: a horse on the inside or a horse on the outside near the rim? ------ outside horse
An industrial flywheel has a greater rotational inertia when most of its mass is  ------ nearest the rim
A coin and a ring roll down an incline starting at the same time.  The one to reach the bottom first will be the ------ coin
Put a pipe over the end of a wrench when trying to turn a stubborn nut on a bolt, to effectively make the wrench handle twice as long, you'll multiply the torque by  ------ two
When a twirling ice skater brings her arms inward, her rotational speed ------ increases
Consider a rotating donut-shaped space habitat where living quarters are on the inside surface farthest from the axis.  If the rotational speed of the habitat increases, the apparent weight of people inside ------ increases
For a system in mechanical equilibrium the resultant forces and torques must ------ both be zero
According to Newton, the greater the masses of interacting objects, the ------ greater the gravitational force between them
According to Newton, doubling the distance between two interacting objects ------ divides by 4 the gravitational force between them
