Centripetal force refers to the force that makes objects move in circular paths. Centripetal force makes an object or body follow a curved path; the direction of the body moves towards the center or fixed point of the circular path.Know More
Depending on the way the force is applied, the path of the body or object in motion may be a slight curve, full circle or cone-like shape. Common examples of centripetal force include the motion of the moon around Earth, swinging a ball on a rope and a race car zooming around a curve.
Centripetal forces are always perpendicular to the motion of the object over a period of time. This relationship causes the object to move along a curved path.
Objects moving in a circular fashion experience acceleration even if moving around the perimeter of the circular shape with constant speed. This acceleration always pushes towards the center of the circle. According to Newton's first law of motion, moving objects naturally want to continue moving in the same direction unless an unbalanced force acts upon the object to knock it off its path. Moving objects naturally travel in straight lines until an unbalanced force requires it to turn or change directions. As a result, unbalanced forces are needed for objects to travel in circles.Learn more about Physics
Force multipliers, also known as simple machines, are devices that are able to provide greater output force than input force. Levers, pulleys, ramps, screws, axles and wedges are all force multipliers that operate using basic physical principles in order to increase output force and make work easier.Full Answer >
Both Isaac Newton and Christiaan Huygens are credited with providing the first scientific and mathematical explanations of the long observed phenomenon of centripetal force. Huygens derived the mathematical formula describing centripetal force in 1659, while Newton defined the scientific concept in his Second Law of Thermodynamics in 1687.Full Answer >
Equilibrant forces are those that act on a body at rest and counteract the force pushing or pulling the body in the opposite direction. Equilibrant forces establish equilibrium for an object and make the object motionless. Equilibrant forces act on virtually every object in the world that is not moving.Full Answer >
If the net force acting on an object is zero, then it means that the object’s velocity is constant and the object isn’t speeding up or slowing down. That is, there is no acceleration on an object with zero net force.Full Answer >
