magnitude of the force‚ d is the object’s displacement‚ and is the angle between the direction of the force and the displacement . Solving simple problems requires substituting values into this equation. More complex problems‚ such as those involving friction‚ often require using Newton’s second law to determine forces. Example: An Eskimo returning from a successful fishing trip pulls a sled loaded with salmon. The total mass of the sled and salmon is 50.0 kg‚ and the Eskimo exerts a force of 120

How a Pogo Stick Works The pogo stick is a mechanical device that utilizes the spring’s ability to store energy. In this paper I will explain how the toy uses the laws of physics to provide hours of fun. There are a lot of forces acting on you and the pogo stick as you bounce along. We’ll take an in depth look at all of these forces and what part they play in the overall functioning of pogo sticks. The physical aspects can be broken down into sections to get a better understanding of what is going

and opposite and equal force on the bottle which pushes the bottle up (3rd law)‚ and the larger that force is‚ the faster it will accelerate and move (2nd law). Eventually the rocket reaches a peak height because external forces (air friction/drag and gravity) act on it (1st law). Now talk about what happens if we add too much water. The mass of the bottle will increase‚ so it takes a larger force to make it accelerate and hence it won’t go as high as when we give

mud is as a lubricant. While drilling process took place‚ there are lots of friction and heat been generated. So mud is needed in order to cool down the temperature and also to reduce the frictions. * The mud also will collect all the debris or the drilled cuttings from the wellbore and transport it to the surface. * The other function of drilling mud is to maintain the stability of the well in terms of friction and pressure. * If the pressure of the well is much higher compare to the
