In motion studies, the position in space and time at which motion began is selected as the
a) home location
b) origin
c) reference point
d) beginning point

b) origin

Explanation:

Motion is when a body changes position in space with respect to time. There are four types of motion namely

1. circular motion: this is the motion of an object along a circular path eg. the motion of a  car tyre.

2. random motion: it is the motion of a body in zigzag manner e.g the motion of smoke from the exhaust pipe of a vehicle as it rises into the atmosphere

3. oscillatory : also known as the to and fro movement of a body e.g a pendulum swing

4. Linear motion: The motion of a body on a straight line. also known as translational motion e.g the motion of a car

Parameters/ terminologies used in motion are

velocity

displacement

distance

acceleration,

time,

speed

Motion in space and time starts from a point known as Origin

c) up is the direction the magnetic force is acting on the charge.
