Work done on an object depends on the distance and force but independent of time.

What is Work ?

Work is the product of force and the distance move in the direction of the force. It is measured in Joule.

If you use more force to move an object, there will be more amount of work because Work done = force x distance.

More force will give more about of work.

If you lift a 20 N object faster, you will experience the same amount of work because work is independent of time.

If you raise an object a shorter height, there will be less work done since work depends on the distance move in the direction of the force.

If you move a lighter object, you will experience a less work done because the weight of the object will reduce the work done

If you move an object farther, there will be more work to be done because of the increase in distance.

Therefore, Work done on an object depends on the distance and force but independent of time.

The scientific symbol are matched with their respective unit of measurement as follows:

  1. Force (F or Fw) = 30 Newton (N).
  2. Work done (W or E) = 90 Joules (J).
  3. Mechanical advantage (MA) = 10 (unitless).
  4. Momentum (p) = 24 kgm/s.
  5. Distance (d) = 25 meters (m).
  6. Power (P) = 8 watts (w).

The amount of work that is required for each situation is given by:

  • More: You use more force to move an object.
  • The same: You lift a 20 N object faster.
  • Less: You raise an object a shorter height.
  • Less: You move a lighter object.
  • More: You move an object farther.

What is a force?

A force (F) can be defined as a push or pull of an object, which typically causes a change of motion (acceleration), especially due to the interaction of the object with another. Also, force (F) is measured in Newton (N).

What is work done?

The work done (W) by an object is calculated by multiplying the force acting on it by the perpendicular distance covered by the object. Thus, work done (W) and energy (E) have the same unit i.e Joules (J).

In this exercise, you're required to match the scientific symbol with their respective unit of measurement and this is represented as follows:

  1. Force (F or Fw) = 30 Newton (N).
  2. Work done (W or E) = 90 Joules (J).
  3. Mechanical advantage (MA) = 10 (unitless).
  4. Momentum (p) = 24 kgm/s.
  5. Distance (d) = 25 meters (m).
  6. Power (P) = 8 watts (w).

Part B.

The amount of work that is required for each situation is given by:

  • More: You use more force to move an object.
  • The same: You lift a 20 N object faster.
  • Less: You raise an object a shorter height.
  • Less: You move a lighter object.
  • More: You move an object farther.
