Question

Science
Mention the different types of motion. Give two examples. for each (any five types of motion)
2 What are scalar's and Vector's ? Give three examples for each.
​

Answer 1

Types of motion

Scientists often make measurements. The physical quantities they measure fall into two categories: scalars and vectors. Scalar and vector quantities are treated differently in calculations.Scalars and vectors - Higher

The direction of movement shows the difference between a scalar and vector quantity – this is the difference between the speed of an object and its velocity.

A physical quantity is something that can be measured.

Scalar quantities only have size (or magnitude).

Vector quantities have size and direction.

Speed is a scalar quantity - direction is not important.

Velocity is a vector quantity – direction is important.

Some scalar quantities you are likely to use in Physics are:

mass

distance

speed

rate of change of speed

time

Some vector quantities you are likely to use in Physics are:

displacement

velocity

acceleration

force

weight

Answer 2

Types of motion

Rectilinear motion - a car moving in a straight line, a straight drive played by a batsman

Circular motion - A Frisbee , a car doing some doughnuts ( google search the term )

Periodic motion - the earth ( rotation and revolution ) , to and fro motion of a pendulum

Rotational motion - blades of a rotating fan , merry go round

Non Periodic motion - car moving on a road , bird gliding in the sky

Vector is a physical quantity that can be measured by both its direction and magnitude. For example - acceleration, force, velocity

Vector is a physical quantity that can be measured by both its direction and magnitude. For example - acceleration, force, velocityScalar is a physical quantity that can be measured by only its magnitude.

Vector is a physical quantity that can be measured by both its direction and magnitude. For example - acceleration, force, velocityScalar is a physical quantity that can be measured by only its magnitude.For example - Mass , length , speed
