Newton`s Laws/ Simple Machine Notes
... For work to be done, something has to move AND the motion must be in the same direction as the force. When work is done, a transfer of energy always occurs. Calculating Work: Work (Joules) = Force (Newtons) times Distance (meters) W= F * D Ex. You push a wheelbarrow with a force of 100N. You moved t ...

What is Work?
... In order for work to be done: • A force must be applied to an object and the object must move a distance. This woman is pushing on the cart (exerting a force) and the cart is moving a distance, so this woman is doing work on the cart. If the woman pushed the cart and the cart did not move, then the ...

Roller Coaster Physics
... Not all of the energy in the roller coaster system is conserved in a non-idealized system. This is because of nonconservative forces. Friction is the main cause of energy leaks in the system and the reason why mechanical energy is not fully conserved. The friction between the train and it’s tracks a ...

Electricity and Energy National 5 Physics Summary Notes
... Any energy which is transformed into a form other than the one we want could be said to be ‘lost’ as it was not intended. Friction will often cause energy loss too. If we want to move an object, we want to change potential energy into kinetic energy, but work done against friction will result in the ...
