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 …
When a force acts on a spring it is stretched or compressed, its length will changes by an amount e from its original length. …
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 …
Stretching or squashing an object can transfer energy into its elastic potential energy store.
What is Elastic potential energy?
Stretching or squashing an object can transfer …
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 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 …
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 …
