The better-known forms of motion include rotary motion (turning round in a circle), linear motion (moving in a straight line), reciprocating motion (moving backward and forward in a straight line), oscillating motion (swinging from side to side), irregular motion (moving with no obvious pattern) and uniform motion (moving at constant speed in a straight line). Kinematics is the science that studies the motion of objects.Continue Reading
Motion is movement, and it can also be defined as a continuous change in the position of an object along a specific vector. Each type of motion is controlled by a different type of force.
There are two types of basic motion. Translation means motion along a path and is defined by the net force (the sum of different forces) acting on an object, while rotation means motion around a fixed axis and is defined by torque (force that causes the rotation of an object).
Many mechanisms take one type of input motion and output it as a different type of motion. For example, a chain and sprocket changes rotary motion to linear motion. A cam and follower changes rotary motion to reciprocating motion, and a peg and slot changes oscillating motion to rotary motion.Learn more about Motion & Mechanics
Objects that move in a circular route at the same speed through multiple revolutions experience uniform circular motion. For this to occur, acceleration of the object on the circular path is dependent upon velocity and the radius of the circle.Full Answer >
Instantaneous speed is an object's rate of motion at a particular time period or moment. Recording the speed of a running cheetah exactly 13 seconds after its sprint began would be an example of instantaneous speed.Full Answer >
The law of inertia states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. The law of inertia is sometimes referred to as Newton's first law of motion.Full Answer >
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 >
