Momentum (p) can be defined and calculated using the following equation: Where m is the mass and v is the…
The work-energy principle states that: The net work done on an object is equal to the change in kinetic energy…
Pressure Pressure – force per unit area. The following equation can be used to calculate pressure (P): Where F is…
Stress Stress (σ) – the force per unit cross sectional area applied to an object. From this definition we have…
If we plot the elastic deformation of a spring we usually get a graph that looks like Graph 1: NOTE:…
If a large enough force is applied to a solid object the shape of the object can change. This change…
Power – the rate at which work is done. From this definition we have the following equation: Where P is…
Kinetic Energy Kinetic energy is the energy an object has due to its motion. In other words it is the…
Energy – the stored ability to do work. There are many forms of energy and each form be transferred from…
Work – the product of force and the distance moved in the direction of the force. We can define work (W) with…
