What is the magnitude of the normal force exerted on the block at the top of the loop? Homework Equations (Flipping the y axis) [tex]N + mg = \frac{mv^2}{R}[/tex] The Attempt at a Solution [tex]N = \frac{mv^2}{R} - mg[/tex] [tex]N = \frac{(1.8kg)(11m/s)^2...
A welded square frame consisting of four equal rods each with mass m and length 2l can move in the vertical plane by means of two small wheels in A and B that move without friction along a horizontal and vertical track, respectively. The disc is released from rest in a position where th...
There are several fundamental forces in nature: the electromagnetic force, the strong nuclear force, the weak nuclear force, and the gravitational force. Answer and Explanation: The normal force can be viewed as a type of force that exists whe...
Whenever you stand somewhere, both gravity and the normal force are at work. You can see this if you stand on a scale. The number that appears is your weight - the force pulling you down to the earth due to gravity. But you could also see this number as the normal force since it'...
Your body has mass and in the earth's gravitational field, your body has weight as well. When you are sitting on a chair and you don't collapse downwards, we can conclude that there is a force supporting and balancing out your weight. That force is opposite and equal and is an ...
Most students think the normal force is always vertically upwards because they look at an object placed on a flat surface like a table. Some of them realize that this is not always the case. For example, an object placed on an inclined plane has a normal force perpendicular to ...
1) Force is a push or pull2) Force is the capacity to do work or cause physical change3) Force= Mass times acceleration (F = ma)4) A force is that which changes or tends to change the state of rest or motion of a body.
If we think about mechanical energy, the energy at humanity's disposal is closer to the storm's, but the task of focusing even half of the energy on a spot in the middle of a remote ocean would still be formidable. Brute force interference with hurricanes doesn't seem promising. ...
