0.  Look around your house for examples; what are the applications of the following topics of Physics 1:
Think about
your everyday activities. Everybody uses physics and engineering
everyday !

1.  What is the SI unit for the following quantities?

2.  What is the weight of 1kg?
Show answer
Multiply mass by 9.8 m/s^{2} (which is also 9.8 N/kg) 
3.  Sketch positiontime diagrams showing:
Check suggested positiontime (pt) graph solutions at Physicsclassroom.com

4.  Sketch velocitytime graph showing the following:
Check shapes and slopes
of velocitytime graph solutions at Physicsclassroom.com for suggested solutions

5.  What is the significance of the area under the following graphs:

6.  Draw freebody diagram of following:
Hint: for each statement, you can draw 2 freebody diagrams, for example, a man pushing a fridge; you can draw freebody diagram (1) for the man and another one (2) for the fridge
Answers to select problems are shown below

7.  What is the definition of momentum?
Show answer
Check your textbook or refer
to class notes.

8.  Did you know that iRobot (located on route 3 in Bedford)
makes robots called Braava and Roomba that
sweep and mop your floor by themselves?
Assume you have one of those robots at home.
When you forget your laptop at home, your
‘smart’ cat learns (from watching some
YouTube videos) how to ride the robot while
the robot is cleaning the floor. Assume your
cat weighs 2 kg and the robot weighs 1.8 kg.
Imbed video here.
Calculate the change in momentum of the Roomba 
9.  Write the formulae for calculating total kinetic energy of a circular disc and a box. Assume both the disc and the box have the same mass, M, and translational velocity, v.
Show answer
Review textbook chapter on translational and rotation kinetic energy.
A rolling disk has translational and
rotation kinetic energy whilst a sliding
box only has translational kinetic energy.
