In physics, motion is a change in position of an object with respect to time and its reference point. Motion is typically described in terms of displacement, direction, velocity, acceleration, and time. Motion is observed by attaching a frame of reference to a body and measuring its change in position relative to that frame. A body which does not move is said to be at rest, motionless, immobile, stationary, or to have constant (time-invariant) position. An object’s motion cannot change unless it is acted upon by a force, as described by Newton’s first law.
Different types of Motion. (We will explore few types of motion in the below simulations)
- Simple harmonic motion – (e.g. pendulum).
- Rectilinear motion (Linear motion) – motion which follows a straight linear path, and whose displacement is exactly the same as its trajectory.
- Brownian motion (i.e. the random movement of particles)
- Circular motion (e.g. the orbits of planets)
- Curve-linear motion – It is defined as the motion along a curved path that may be planar or in three dimensions.
- Rolling motion – (e.g. the wheel of a bicycle)
