Homework Help: Physics check

Posted by Jon on Monday, April 14, 2008 at 7:20pm.

1)What can you say about the motion of a body if:
a. its displacement-time graph is a straight line inclined with the time axis
b. its velocity-time graph is a straight line inclined with the same axis.
c. its velocity- time graph is a parabola

A)The velocity is constant and it is equal to the slope.

B)The acceleration is constant and equal to the slope of the line.

C)The acceleration is time dependent and is still equal to the slope of the line.

2)What conclusions can be drawn if a velocity-time graph is parallel to the time axis?

The object is moving at a constant rate.
