### Archimedes Principle

The relationship between buoyancy and displaced fluid: An immersed object is buoyed up by a force equal to the weight of the fluid it displaces

### Bernoulli's Principle

The statement that the pressure in a fluid decreases as the speed of the fluid increases

### Hooke's Law

The distance of stretch or squeeze (extension or compression) of an elastic material is directly proportional to the force applied

### Universal Gravitation

For any pair of objects, each object attracts the other object with a force that is directly proportional to the product of the masses of the objects, and inversely proportional to the square of the distance between their centers of mass.

### Inverse Square Law

A physical quantity varies inversely as another quantity squared.

### Law of Conservation of Energy

Energy cannot be created or destroyed. It may be transformed from one form into another, but the total amount of energy never changes.

### Law of Conservation of Momentum

In the absence of a net external force, the momentum of an object or system of objects is unchanged.

### Law of Inertia

Every body continues in its state of rest, or motion in a straight line at constant speed, unless acted on by a nonzero force.

### Newtons 1st Law

Law of inertia- Every body continues in its state of rest, or motion in a straight line at constant speed, unless acted on by a nonzero force.

### Newtons 2nd Law

The acceleration produces by a net force on a body is directly proportional to ehe magnitude of the net force, is in the same direction as the net force, and is inversely propotional to the mass of the body.

### Newtons 3rd Law

Whenever one body exerts a force on a second body, the second body exerts an equal and opposite force on the first

### Newtons Law of Cooling

The rate of cooling of an object-whether by conduction, convection, or radiation-is approximately propotional to the magnitude of the net force, is in the same direction as the net force, and is inversely proportional to the mass of the body

### Conservation of Angular Momentum

An object or system of objects will maintain a constant angular momentum unless acted on by an unbalanced external torque

### Pascals Principle

Changes in pressure at any point in an enclosed fluid at rest are transmitter undiminished to all points in the fluid and act in all directions.
