velocity

Answer 1

Step-by-step 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
