Question

defin work and energy

Answer 1

In physics, a force is said to do work if, when acting, there is a displacement of the point of application in the direction of the force. For example, when a ball is held above the ground and then dropped, the work done on the ball as it falls is equal to the weight of the ball (a force) multiplied by the distance to the ground (a displacement).

In physics, energy is the quantitative propertythat must be transferred to an object in order to perform work on, or to heat, the object.

Answer 2

$\bold{work - } \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \bold{work \: is \: said \: to \: be \: done \: by \: a \: force \: when \: a \: body \: gets \: displaced \: in \: the \: direction \: of \: force} \\ \red{work = force \times distance} \\ \bold{energy - } \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \bold{the \: capacity \: of \: a \: body \: to \: do \: work \: is \: called \: energy}$
