I.
Identification. Identify the following.
1. It
is a subbranch of classical physics that focuses on forces acting on bodies
whether at rest or in motion.
2. Object
or background used for comparing different positions of an object.
3. Refers
to the movement of an object.
4. Motion
of an object travelling in a curved path.
5. Continuous
change of position with respect to a certain reference point.
6. It
is the symbol for distance
7. It
is exhibited by a change in position.
8. Motion
of an object travelling in a straight path.
9. The
total length of a path travelled or covered by an object.
10. Motion
of an object travelling in a straight path.
11. It
focuses on the way in which forces combine with each other so as to produce
equilibrium.
12. Straight
line distance between the starting and end points.
13. It
focuses on the way in which force produces motion.
14. It
focuses on the motion of a body without regard to the cause of that motion.
15. It
is the symbol of displacement.
II.

under Kinematics, Dynamics and Statics.
1. hanging

4. pulling
a toy car
5. stationary
cabinet
6. the

III.
Problem Solving. Solve for the distance and
displacement in the following problem. Show your complete solution.
1. A
boy walks 7 km West then 4 km North and finally 4 km East. How far is he from
his starting position? What is the total distance of the boy?
2. To
get from one office to another in Makati, one travels as follows (with all
angles measured clockwise from the West): 2 m at 180⁰, 0.5 m at 150⁰ and 1.0 m
at 30⁰. Find the total distance and the displacement.
