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
The law of inertia is a fundamental physics principle used to describe how an object behaves in motion or at rest, particularly when forces are applied to it. The object can be anything that has mass.Full Answer >
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 >
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 >
Unbalanced force occurs when two forces acting on an object are not equal in size, causing a change in motion. Unbalanced forces cause a still object to move or moving objects to slow down or speed up, stop or change direction.Full Answer >
