Physics Set #1

Your pet hamster sits on a record player whose angular speed is constant. If he moves to a point twice as far from the center, then his linear speed

Which moves faster in m/s on a merry-go-around: a horse on the inside or a horse on the outside near the outer rail?

If a turntable rotational speed is doubled, then the linear speed of a pet hamster sitting on the edge of the record will

Suppose the circumference of a bicycle wheel is 2 meters. If it rotates at 1 revolution per second when you are riding the bicycle, then your speed will be

An industrial flywheel has a greater rotational inertia when most of its mass is

A coin and a ring of equal masses and equal diameters roll down an incline, starting from rest at the same time. The one to reach the bottom first will be

A torque acting on an object tends to produce

On a balanced seesaw, a boy three times as heavy as his partner sits:

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 will multiply the torque by

A leaning tower of Pisa doesn't topple over because its center of gravity is

A chef at a pizzeria tosses a spinning disk of unbaked pizza dough into the air. The disk dismeter increases during the flight, while its rotational speed

Centrifugal forces are an apparent reality to observers in a reference frame that is

A person weighs less at the equator than at the poles. The main reason for this has to do with

When a twirling ice skater brings her arms inward, her rotational speed

Consider a rotating donut-shaped space habitat, where living quarters are on the inside surface fartherst from the axis of rotation. If the rotational speed of the habitat increases, the apparent weight of people inside
