Turning Moments
The size of the turning effect is called a turning moment. As Newton's first law of motion states, an object will remain at rest if the forces are balanced. When the sum of the forces add to zero, a body will remain at rest or move at a constant velocity.
Moments
Forces can cause an object to rotate and the turning effect of the force is called a moment. If a resultant force acts on an object about a fixed turning point called the pivot or fulcrum it will cause the object to rotate e.g. using a spanner, a screwdriver, opening a door hanging on hinges.
Force on a Spring
When a force acts on a spring it is stretched or compressed, its length will changes by an amount e from its original length.
…
Pressure
Pressure can be calculated if you know the force applied to or by an object and the contact area. The units are newtons per square meter, or N/m2.
Force, Mass and Acceleration
An object of constant mass accelerates in proportion to the force applied.
Kinetic Energy
In physics, the kinetic energy (KE) of an object is the energy that it has due to its motion. It is defined as the work needed for an object of a known mass to accelerate to a given velocity.

Specific Heat Capacity
Specific heat capacity is how much heat energy is required to raise 1 kg of a substance by 1 °C.
