Question

Draw the graph for following situations
a. Object at zero acceleration is (s-t, v-t)
b. Obiect falling freely under gravity (v-t)​

Answer 1

Explanation:

1) object at zero acceleration :

a) s-t  Graph:

Let the velocity be 'u' .

So,

S= ut

Linear equation

=> Represents straight line with finite slope.

b) v-t Graph:

a=0;

Using Newton's Equation,

v=u+at=u (constant)

=> straight line with zero slope.

2) Object falling freely under gravity.

a = -g (acceleration due to gravity)

Assuming zero initial velocity.

using Newton's Equation ,

v=u+at

 = 0-gt

=> straight line with negative slope.

All figures are attached respectively.
