explain story behind motion.
Answers
In physics, motion is the phenomenon in which an object changes its position over time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed, and time. The motion of a body is observed by attaching a frame of reference to an observer and measuring the change in position of the body relative to that frame with change in time. The branch of physics describing the motion of objects without reference to its cause is kinematics; the branch studying forces and their effect on motion is dynamics.
Motion and Terms
- Motion is the process of something moving or changing place, or even just changing position.
- Speed is how long it takes for an object to travel a certain distance. ...
- Velocity and speed are very close and often mixed up. ...
- Acceleration is when any part of an object's velocity changes.
What are the causes of motions?
Motion is caused by forces. A stationary object does not move unless a force acts on it to start it going. Once it is moving, it carries on at the same speed and in the same direction unless a force makes it speed up, change direction or slow down and stop
