Dynamics-II

A tightrope walker is carrying a long pole while walking across a rope. The stability of the walker is affected if the pole is:

A car drives at a steady speed around a perfectly circular track.

If a body is at rest or moving with uniform rotational velocity, then torque acting on the body will be:

A body in equilibrium must not have:

Seesaw balances perfectly with two children of equal weight sitting at equal distances from the fulcrum. If one child moves closer to the fulcrum:

You are trying to loosen a nut using a spanner, but it is not working. In order to open the nut, you need to:

You throw a weighted fishing net into a calm lake. As the net sinks, it opens fully underwater, spreading out its mesh evenly. Compared to the moment it left your hand, where is the net’s center of mass now?

A satellite of mass ‘m’ is revolving around the Earth with an orbital speed V. If the mass of the satellite is doubled, its orbital speed will become:

The force that always changes the direction of velocity and not its magnitude is called:

When the line of action of the applied force passes through its pivot point then the moment of force acting on the body is:

A uniformly rotating fan is said to be in:

The correct order of comparison for the terminal speeds of a raindrop, snowflake, and hailstone is:

For an object moving with terminal velocity, its acceleration:

It is more difficult to walk on a slippery surface than on a non-slippery one because of:

The reason that a car moving on a horizontal road gets thrown out of the road while taking a turn is:
