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.
Continue ReadingThrowing an object upward on the surface of the Earth introduces two forces on the object — an upward force that is opposed by the force of gravity and a forward force. Eventually, the gravitational force will overcome the upward force. The arc of the object's path is a parabola.
The first research on parabolic trajectories was done in the early 17th century by noted Italian physicist and mathematician Galileo Galilei; some of his initial experiments involved rolling uniform balls along inclined planes.

The law of inertia is sometimes referred to as Newton's first law of motion.
Full Answer >The energy of an object in motion is known as kinetic energy. There is more kinetic energy in an object that is heavier and faster. Several types of kinetic energy exist, including vibrational, rotational and translational.
Full Answer >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.
Full Answer >Because any moving thing or object has kinetic energy, there are many examples of this energy type, including a ball dropping into water, a car in motion and a moving arrow. However, there are different types or forms of kinetic energy.
