When a body or object moves in a circle, it is said to be in a circular motion. That is we can say that motion in a circle is a circular motion. When a body or object moves along a circular path, then ...

6.In uniform circular motion, the centripetal force acting on an object is: (a) Parallel to the motion of the object. (b) Perpendicular to the motion of the object. (c) Opposite to the motion of the ...

Polar orbits take the satellites over the Earth's poles. The satellites travel very close to the Earth (as low as 200 km above sea level), so they must travel at very high speeds (nearly 8,000 m/s).

Centripetal and centrifugal forces are central to circular motion, but they're not the same. Discover the differences between the two often-confused forces.

In physics, motion is a change in position of an object with respect to time and its reference point. Motion is typically described in terms of displacement,velocity, acceleration, and time. Motion is ...

Physics, particularly forces and motion, can be challenging. By observing everyday motion, conducting simple experiments, and understanding Newton's laws in plain language, the concepts become more ...

One of the physics blogs I read regularly is ZapperZ's Physics and Physicists, where last week he posted an interesting observation about the difference between subjects when it comes to modes of ...

One of the funny things about living on a big spinning ball of rock and metal in space is that what you see depends on where you are. Where I live, in Colorado, the Sun rises every day, makes an arc ...
