done=force x distance What is work? Work in physics is the transfer of energy; work is done on an object when an applied force moves it through a distance. The link between work and energy is work done equals energy transferred. The units for the two are also the same (joules). E.g. 500J of work = 500J of kinetic energy. Work is calculated with the formula: work done=force x distance moved For example‚ if a force of 10 newton (F = 10 N) acts along point that travels 2 meters (d = 2 m)‚ then it does

What outrages you? What are you doing about it? 1000 characters “I don’t know”‚ one of the most common phrases which is a limit we place on ourselves. We accept our lack of knowledge and prevent further thought. A limit is defined as “something that bounds or confines”. Nothing drives me crazier than watching this. Accepting a limit creates a comfort zone that does not allow for improvement. Through coaching and tutoring I am able to help others challenge themselves. Coaching‚ I was introduced

Which Dress Do You Like Best? The following memory I will outline may seem an excessively informal anecdote for a paper as such but it reveals truth in the point I will be presenting.

The drill consisted of trying on several dresses and asking the two other friends their opinion‚ when we found a dress that all three agreed on (given the price

What is kinetic energy? Kinetic energy is energy due to object’s motion. Kinetic energy of an object depends on both its mass and its speed. Kinetic energy increases when mass increases. You can find kinetic energy by using the formula kinetic energy equals one half times mass times speed to the second power. What is potential energy? Some objects have stored energy as a result of their positions or shape.Potential energy is stored energy that results from the position or shape of an object.
