Question

Please answer this questions ​

Answer 1

Answer:

1). The product of force and displacement is called work.

Work= Force*displacement

W=F*s

2).Law of conservation of energy states that energy can neither be created nor be destroy it can only be transformed into different form.

3). 1/2mv²

Use the equation of motion here v²-u²=2as

4). A book on table before it fall

River water at top of waterfall

A child at top of the slide.

Answer 2

Explanation:

1). The product of force and displacement is called work.

Work Force displacement

W=F×s
