force
... This object is moving in a circular path at a constant speed. The string is constantly exerting a force on the object At any point in time, there is a net force on the object (no opposite forces) According to Newton’s First Law, the object must be accelerating. How? It is moving at a constant speed. ...

Intro to EMR and Wave Equation
... •In a vacuum, all EMR travel at the speed of light regardless of frequency •19th century physics theory said all waves had to travel through something, the medium that EMR moved was called the ether (a transparent substance that filled all space) •Experiments were done to measure the speed of light ...

Force and Motion
... What 2 things do you need to know in order to find the velocity? Explain the difference between acceleration and force. Both ____ and ____ depend on mass. What causes an object’s speed or direction to change? Define momentum. Share with a partner one thing you learned about force and motion. ...

... This particle accelerator cannot be used to accelerate electrons or negatively charged ions to high energy particles. As the electrons are small, soon these electrons reach the speed of light, hence the mass changes. As the mass changes the frequency will not match with the frequency of the suppl ...
