Question

PHYSICS
Fill in the blanks
1. When s-t graph is parallel to x-axis, the body is
2. When v-t graph is parallel to x-axis, the body is
3. The slope of vt graph for a body in uniformly accelerated motion is
4. The slope of displacement-time graph for a car parked in a parking area is_
5. Acceleration is a
quantity​

Answer 1

Answer:

As we know that

1.Rate of change of displacement(d) with respect to time is known as velocity(v).

  $v=\dfrac{ds}{dt}$

The slope of distance -time graph is equal to velocity.

2.Rate of change of displacement(d) with respect to time is known as velocity(v).

  $a=\dfrac{dv}{dt}$

The slope of velocity -time graph is equal to acceleration.

-----------------------------------------------------------------------------------------------------------

1. The body is in rest position because slope of s-t graph is zero.

2.The body is in rest uniform velocity because slope of v-t  graph is zero.

3.The slope of the v-t graph is positive.

4.Velocity is the slope of displacement-time graph.

5.Acceleration is a vector quantity​.
