After studying this unit, the students will be able to:
describe using examples how objects can be at rest and in motion simultaneously.
identify different types of motion i.e. translator/, (linear, random, and circular); rotatory and vibratory motions and distinguish among them.
differentiate with examples between distance and displacement, speed and velocity.
differentiate with examples between scalar and vector quantities.
represent vector quantities by drawing. define the terms speed, velocity and acceleration.
plot and interpret distance-time graph and speed-time graph.
determine and interpret the slope of distancetime and speed-time graph. determine from the shape of the graph, the state of a body
i. at rest
ii. moving with constant speed
iii. moving with variable speed.
calculate the area under speed-time graph to determine the distance travelled by the moving body.
derive equations of motion for a body moving with uniform acceleration in a straight line using graph.
solve problems related to uniformly accelerated motion using appropriate equations.
solve problems related to freely falling bodies using 10 ms^-2 as the acceleration due to gravity.

Aim and Purposes:
Education is very expensive nowadays. Our only purpose is to educate everyone for free. We want to bring an educational revolution. Our aim is that nobody should be left behind, everyone should get knowledge and quench his thirst for knowledge. For this noble cause, we have hired a lot of experienced teachers and technical experts, who are serving you without any cost. If you want to be a part of this noble cause, you can contact us at email@example.com
Report a mistake:
EducatedZone has been working for the help of students since 2017. With the passage of time, many senior students and teachers have joined our team to become the part of this noble cause. They provide us notes and helping material to share with public. As different persons are notes provider so there may be a chance of mistake in some notes. Although it happens rarely, but if you find some mistake in the helping material, you can report it at firstname.lastname@example.org
