When you push an object, you are doing work. Work is the transfer of energy that occurs when a force is applied to an object, causing it to move in the direction of the force. Pushing involves exerting a force on an object to move it.
The work done against gravity is given by: W = mgh = (380 kg)(9.8 m/s^2)(170 m)sin(7.5º) The work done against friction is given by: W_friction = f_friction * d = µ * m * g * d, where d is the distance moved. The total work done is the sum of the work against gravity and friction: Total work = W + W_friction.
A push or pull that acts on an object is a force.
Air resistance
The energy lost in doing work against friction is primarily converted into heat energy. Friction between surfaces causes mechanical energy to be transformed into thermal energy, leading to an increase in temperature in the system.
The factors that affect the ability of gravity to do work include the distance the object falls, the mass of the object, and the presence of other forces that may oppose gravity, such as friction or air resistance. The work done by gravity is determined by the height through which the object falls and the force of gravity acting on the object.
In this case, you are not doing work against the force of gravity, but against the force of friction.

The work done against gravity is given by: W = mgh = (380 kg)(9.8 m/s^2)(170 m)sin(7.5º) The work done against friction is given by: W_friction = f_friction * d = µ * m * g * d, where d is the distance moved. The total work done is the sum of the work against gravity and friction: Total work = W + W_friction.

A push or pull that acts on an object is a force.
Air resistance
the two forces are friction and gravity
outer space travel work by gravity and friction plus magentism

it is because the displacement of load being horizontal,is normal to the direction of force of gravity ie.,cos 90' which is zero but he surely does some work if we consider it against the force of friction.

Friction is important on a water slide as it helps slow down the rider's speed to ensure a safe descent. Gravity, on the other hand, provides the force that pulls the rider down the slide. Together, friction and gravity work in harmony to control the speed and movement of the rider on a water slide.
