Answer 1

Answer:

Distance�Time Graphs

• For a body at rest

• As the slope is zero, so speed of the body is zero.

• For a body moving with uniform speed

• For accelerated motion.

• The slope of graph is increasing with time

• For decelerated (speeding down) motion.

• Slope of graph is decreasing with time

Velocity�Time Graphs

• When a body moving with a uniform velocity.

• The slope of AB indicates zero acceleration

• When a body starts from rest and moves with uniform acceleration.

• Greater is the slope of v-t graph, greater will be the acceleration

• When a body is moving with uniform acceleration and its initial velocity is not zero.

• When a body is moving with increasing acceleration.

• Slope increases with time.

• When a body is moving with
