5 days ago · Spring Force - It is a type of restoring force. This is because the force exerted by the spring is always in the opposite direction to the displacement. Nuclear Force - It is a force that acts between all the particles in the nucleus. That is the force acting between two neutrons, between two protons and between a neutron and a proton.
- 1. What is the difference between thrust and pressure?Thrust is the total force acting perpendicular on a given surface, while pressure is the thrust acting upon a unit area. Also, thrust is the amount...
- 2. What is magnetic pressure?A magnetic field has a magnetic pressure within the boundary conditions. The magnetic field gradient causes a force due to the pressure gradient. T...

5 days ago · An earthquake is an intense shaking of Earth’s surface. The shaking is caused by movements in Earth’s outermost layer. Why Do Earthquakes Happen? Although the Earth looks like a pretty solid place from the surface, it’s actually extremely active just below the surface.
4 days ago · Explain the cause-and-effect relationship between the forces responsible for rotary motion and the objects experiencing the motion. Define centripetal and centrifugal force, and explain the relationships that exist between these forces and the factors influencing them.
5 days ago · The Short Answer: A galaxy is a huge collection of gas, dust, and billions of stars and their solar systems, all held together by gravity. We live on a planet called Earth that is part of our solar system. But where is our solar system? It’s a small part of the Milky Way Galaxy.
Name, define, and use the following terms properly as they relate to rotary motion: eccentric force, torque, couple, lever, moment of inertia, and angular momentum. 2. Solve simple lever and torque problems involving the human body and the implements it uses.
