Gas Pressure is created when gas particles collide with the walls of their container. The more often the particles collide with the walls, and the faster …
Wave speed is given in meters per second (the number of waves that pass per second). Wavelength is measured in meters and frequency is measured …
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 …
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 …
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 can be calculated if you know the force applied to or by an object and the contact area. The units are newtons per square …
An object of constant mass accelerates in proportion to the force applied.
Demo
In this tutorial you will learn how to calculate the force applied to an object if you …
The unit for work done is the joule (J), or Newton meter (N-m). One joule is equal to the amount of work that is done when 1 N of force moves an …
All moving objects have momentum. Forces can cause changes in momentum. The total momentum in a collision or explosion is conserved and stays the …

The period of a wave is the time it takes to complete one cycle. The unit for a wave period is seconds, and it is inversely proportional …
A transformer is an piece of electrical apparatus which will increase or decrease the voltage in an alternating current. It can be designed to “step up” …
A current-carrying wire or coil can exert a force on a permanent magnet. The force increases if the strength of the magnetic field and/or current increases. This is …
The magnification can be calculated if you know the actual size of the object and its image size.
Demo
In this tutorial you will learn how to calculate …
Uniform or constant acceleration is a type of motion in which the velocity of an object changes by an equal amount in every equal time period.
Demo
In …
Fluid pressure is exerted on the surface of an object in a liquid. This pressure causes upthrust . An object placed in a liquid will begin to sink. …
Acceleration is how quickly the velocity is changing whether it be speed, direction or both. Acceleration is a measure of how quickly the velocity …
Speed is how fast an object is moving in no given direction. Velocity is how fast an object is moving in a given direction. …
Weight is the force acting on an object due to gravity. The weight of an object is defined as the force of gravity on the object …
