Forces are needed to lift, turn, move, open, close, push, pull, and so on. When you throw a ball, you are using force to make the ball move through the air. More than one force can act on an object at the same time.
Explanation:
the force acting perpendicularly on unit area of surface
- unit=pascle .
work is force x distance = 25 x 0.4
= 2.5x4 = 10joules
pwer would be 10j/2s watts .... 5 watts
Answer: D!
It is the option with the greatest amplitude.
Answer:
When work is positive, the environment does work on an object.
Explanation:
According to the work-energy theorem, the net work done by the forces on a body or an object is equal to the change produced in the kinetic energy of the body or an object.
The concept that summarizes a concept related to the work-energy theorem is that ''When work is positive, the environment does work on an object.''
