hey buddy here is your

work is a product of force and distance

explanation:

according to physics,work is said to be done when there is displacement in the direction of force

si unit:joule(j)

b. lifting dumbbell weight at 20-degree angle from the body after a 45-degree angle

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
