Circular motion happens when an object moves around a point in space, never getting farther from it or closer to it. The distance from the center point is the radius of the circle.Know More
In order to travel in a circular motion, an object must constantly change direction. Though its path forms a circle, the object is always moving tangentially to the circle. One tangent is simply interrupted by the next with each tiny directional shift.
When the object travels at the same speed around the point, it has uniform circular motion. According to Newton's second law, an object in uniform circular motion will also experience a force in the direction of the center point.Learn more about Motion & Mechanics
The path taken by a flying object in motion on the surface of the Earth is called a parabola. A parabola is a symmetrical arc, and the trajectory of flying objects with negligible air resistance in a gravitational field, as on the surface of the Earth, follows this path.Full Answer >
Kinetic energy is used by exploiting the motion of an object. For example, the energy of a moving piston in an automotive engine provides transportation. The kinetic energy of moving water powers hydroelectric dams that provide electricity.Full Answer >
Friction is a force that opposes motion, so it is unhelpful in all situations where the motion of an object is desired. A by-product of friction is that energy is wasted in the form of heat, which can cause problems in temperature-sensitive environments.Full Answer >
Force and motion are related because exerting force on an object causes a change in motion. An example would be kicking a ball to propel it forward. Two examples of natural forces are gravity and magnetism.Full Answer >
