Decrease his rotational inertia

Increase his rotational inertia

A tin can whirled on the end of a string moves in a circle because

there is an inward force acting on the can.

Where is the center of gravity of a softball bat located?

In the more massive end of the bat

Which would have a greater linear velocity?

Kid near the outside of the merry go round

Kid near the center of the merry go round

Why are you more stable when riding a bicycle at a faster speed?

The wheels have angular momentum

It's not easier to ride at a faster speed

When you carry a heavy load with one arm, why do you tend to hold your free arm away from your body?

To change the center of gravity of your body and the load

To change the mass of your body

To be ready to grab something in case you fall

Does a bridge anchored resting on two pillars have any torque?

Yes, but it will soon break because of the torque

The center of mass is:

the point at which you can balance with one finger

the idea that mass is concentrated throughout

Stars originate as large bodies of slowly rotating gas. Because of gravity, these clumps of gas slowly decrease in size. What happens to the angular speed of the start as it shrinks?

It starts to accelerate in the forward direction.

The rotation rate stays the same.

You are making a circular turn in your car on a horizontal road when you hit a big patch of ice, causing the force of friction between the tires and the road to become zero. While the car is on the ice, it

moves along a straight-line path in its original direction.

continues to follow a circular path, but with a radius larger than the original radius.

moves along a straight-line path toward the center of the circle.

moves along a straight-line path away from the center of the circle

When a car goes around a circular curve on a horizontal road at constant speed, what force causes it to follow the circular path?

the friction force from the road

No force causes the car to do this because the car is traveling at constant speed and therefore has no acceleration.

Jack and Rose are holding hands and spinning in a circle as fast as they can. If rose lets go by accident, what can you say about Jack's motion?

it will be in a straight line in the direction of the instantaneous velocity

it will be in a straight line opposite of Rose

it will be in a curved path in the direction that he was originally going

Rose said she would never let go... she lied

Moment of Inertia of a body about an axis of rotation depends

D. All of the answers are true.

C. Distribution of mass about the C. axis of rotation

For a rotating rigid body, which of the following statements is NOT correct?

All points along a rotating rigid body move with constant speed

Points along a rotating body have velocities that continuously change directions

Points along a rotating body move through the same angle in equal time intervals

A radian is all of the following EXCEPT

The ratio of arc length over radius

The unit for rotational position

Which one of the following statements concerning the moment of inertia I is false? (AP Extension)

depends on the angular acceleration of the object as it rotates.

may be expressed in units of kgm 2 .

depends on the location of the rotation axis relative to the particles that make up the object.

depends on the orientation of the rotation axis relative to the particles that make up the object.

of the particles that make up an object, the particle with the smallest mass may contribute the greatest amount to I .

The easiest way to open a heavy door is by applying the force

At the edge of the door far from the hinges

What force does not cause any torque?

Force perpendicular to the fulcrum.

Force horizontal to the planck.

Force slightly off center of the fulcrum

Forces at a 45 degree angle to the fulcrum, and not on the fulcrum

A seesaw with mass x is perfectly balanced with a fulcrum in the center. If mass x changes uniformly does the net torque change?

No, because it is balanced that means net torque is zero, a uniform increase in weight keeps it balanced keeping net torque at zero

Yes, because the Gravitational force increases with more mass, and torque is related to Force

No, because the net torque is still zero despite increases in one of the individual components.

Yes, any increase in weight will increase torque

You apply force to a wrench to tighten a bolt. The wrench breaks in half. Select the best answer for what happens next. Assume the force applied remains constant.

The torque is now half of what it was, because torque and distance are directly proportional

The torque is now half of what it was, because torque and distance are inversely proportional

The torque is now double of what it was, because torque and distance are inversely proportional

The torque is now double of what it was, because torque and distance are directly proportional

What is the direction of a centripetal force?

Inward and perpendicular to the motion of the object

In the same direction that the object is moving

Outward and perpendicular to the motion of the object

A small but hard nut must be crushed. Which position will require more squeezing force by a hand?

It doesn't matter which position the nut is in.

What will happen to the torque and speed of gear B?

Increased torque, decreased speed

Increased torque, increased speed

Decreased torque, decreased speed

Decreased torque, increased speed

What will happen to the torque and speed of gear A?

Decreased torque, increased speed

Increased torque, increased speed

Decreased torque, decreased speed

Increased torque, decreased speed
