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
Force is any influence to an object which changes its motion, while motion itself is the change in position of an object in relation to is speed, location and acceleration. There cannot be movement without force used against an object to set it in motion.Full Answer >
Projectile motion is caused by gravity's effect on the path of any object that is launched or thrown, according to HowStuffWorks. Projectile motion has both horizontal and vertical components. The horizontal component is due to the velocity of the object, while the vertical component is due to the force of gravity.Full Answer >
According to the Physics Classroom, projectile motion occurs when an object that is at rest or something close to rest is projected or dropped. An object under projectile motion is an object upon which the only acting force is gravity.Full Answer >
Newton's first law states, "Every object persists in its state of rest or uniform motion in a straight line unless it is compelled to change that state by forces impressed on it." A more colloquial way of saying it is "an object in motion stays in motion."Full Answer >
