"All objects with mass attract and are attracted by all other objects with mass because of a force called gravity. The strength of gravity is proportional to the mass of the object. We are pulled to t ...

"Gravitational fields are vector fields that show forces of gravity around a large object. A gravitational field pulls all surrounding objects towards the center of mass but pulls the matter at the ce ...

"The two most commonly used graphs of motion are velocity (distance v. time) and acceleration (velocity v. time). In each case, time is shown on the x-axis. The graph of velocity is a curve while the ...

"States of matter are the different phases which matters can take - gas, liquid and solid. Gas has no fixed shape and conforms to the volume of its container. A liquid has a distinct volume but assume ...

"Standing waves, also known as stationary waves, are waves formed by the combination of two waves with equal amplitudes and frequencies. Because of the interference between these waves, standing waves ...

"The standing sound waves are known as harmonics that involved sound. Standing sound waves associate with the boundary conditions at the boundaries of the medium. When the traveling wave is reflected ...
"Spring potential energy is the store energy that drives the restoring force described in Hooke's Law. Other than Hooke's Law, the equation for the potential energy function, U=1/2kx^2, is essentially ...

"Speed refers to the rate at which an object travels. Unlike velocity, speed is a scalar quantity so direction does not matter. Instantaneous speed is the speed of an object in motion at a specific po ...

"Sound waves are waves transmitted through the air or even through liquids or solids which change the pressure of that substance enough that our ears can perceive them. The pitches of sounds we hear d ...

"The frequency of a wave measures how often it passes a given point in a given length of time. A wave's period measures how long it takes for a wave to pass a given point in its entirety, from crest t ...
