Answer:
Explanation:
1. Physics is the study of mass , energy and their mutual relationship.
2. List the fundamental Sl (metric) units for:
time - s,
displacement - m,
velocity - ms,
acceleration- m/s2,
force - N,
weight - Kg,
mass- kg
friction - N.
3. On a "position vs. time" graph, how is velocity found?
A straight line will obtained.
4. On a "position vs. time" graph, how is acceleration represented?
Under the slope of straight line.
5. 32,000 m = 32km
25 m/s = 55.9 miles/hr
50 km/hr = 13.9m/s
6. (2.0 x 105 km) (3.1 x 1012 m) = 658 812 000 m2
7. Describe the motion of the object whose velocity is illustrated in the graph below:
velocity
