Do forces always act alone?
The statement “Forces always act alone” is false. Force do not always act alone. It is always accompanied by another force that is always opposite to it.
When you whirl a can at the end of a string?
Example: If you whirl a tin can on the end of a string, you must keep pulling on the string—exerting a centripetal force. The force exerted on a whirling can is toward the center. No outward force acts on the can. Joe is sitting 2m from the center of a merry-go-round that has a frequency of 1.

Does an inward or an outward force act on the clothes during the spin cycle of an automatic washer?
In an automatic washing machine, inward force is exerted on the clothes during the spin cycle or whirling because of the wall of the machine, which…
Where is the center of mass of a baseball where is the center of gravity?
Where is the center of mass of a baseball? Where is its center of gravity? The center of mass and the center of gravity are both at the center of the spherical ball.
Where is the center of gravity of the broom that Dr Hewitt holds up?
Where is the center of gravity of the broom that Dr. Hewitt holds up? The shorter side, where the bristles of the broom are, has a greater weight than the handle.
Is the net torque change when a partner on a seesaw?
Its mass is near the rotational axis that extends through its center of mass. Is the net torque changed when a partner on a seesaw stands or hangs from her end instad of sitting. The net torque stays the same. The lever arm will stay the same whether a person stands, sits or hangs from the end.
Which will have the greater acceleration rolling down an incline a large ball or a small ball?
Which will have the greater acceleration rolling down an incline – a large ball or a small ball? They would have the same acceleration.
What is the net torque on the seesaw?
The net torque on the seesaw could be zero, but the seesaw could rotate with a contant angular speed.
Is seesaw a torque?
Seesaws are a good example of torque in our daily life.
What happens when net torque not zero?
Because there is no net torque acting on an object in equilibrium, an object at rest will stay at rest, and an object in constant angular motion will stay in angular motion. Because the net torque is equal to zero, the torques in Example 1 are balanced and acting in equilibrium.
