The equation that links force, distance and work isWork done = Force X DistanceThis can be rearranged to giveForce = Work done / DistancePlug the values from the question into the equation to give the calculationForce = 640/8Therefore the force equals 80 Newtons
Yes, and the strength of the force is equal to the weight of the fluid displaced by the body.True

That is called impulse; the equation is Ft = mv
Newton's First Law of Motion states that objects will remain in their current state of motion (whether stationary or travelling at a constant velocity) unless an outside force acts on them. If he force you are mentioning here causes the net force to become unbalanced, then the force will cause the object to accelerate until the forces are balanced and it reaches either a constant speed, or the opposing force causes it to decelerate and eventually become stationary.

Lever In physics, a lever (from French lever, "to raise", c.f. a levant) is a rigid object that is used with an appropriate fulcrum or pivot point to multiply the mechanical force that can be applied to another object.

The way torque works, these two cases give the same torque, or twisting force, to the object at the pivot point. To find the torque applied, multiply the force by the distance. Obviously this is the same in the two cases you describe.
