Force, Energy and Power
Components of Force
Any force applied at an angle can be separated into two components as it is a vector quantity. we can do this by using trigonometry
Masses on a inclined plane, these conditions allow for us to be able to calculate the components of force on an object down a slope. The normal/reactionary force is the force perpendicular to the surface. The parallel component of the force is the force acting on the mass which causes motion.
Energy
Work, this is the product of force and distance giving us the energy of an object moving with a force.
Kinetic Energy, is the energy gained by a moving object. This energy is associated with movement and therefore can be used in tandem with potential energy to calculate speeds of falling projectiles.
Potential Energy, is derived from the work function which is the energy contained in a system when a force is applied to add energy into a system, this is usually done by height or the compression of a spring. for a difference in height the equation for potential energy is,
falling velocity formula, we get this from setting the Ke=Pe and then simplifying.
Energy is measured in joules, and is the concept we use to define any interaction between matter, forces and waves..
Power
Power is the rate at which energy is used and converted, Power is therefore the amount of energy converted per unit time.
