The displacement of a moving object in a given interval of time is zero. Would the distance travelled by the object also be zero ? Justify you answer.
When the displacement is zero, it does not mean that distance is also zero. Displacement can be zero when the moving object comes back to its original position. Displacement is either equal to or less than distance but distance travelled is always more than zero.
What can you conclude about the motion of a body depicted by the velocity$-$time graphs $(i),(i i)$ and $(i i i)$ given below
The velocity$-$time graph of a car is given below. The car weighs $1000\, kg$.
$(i)$ What is the distance travelled by the car in the first $2$ seconds ?
$(ii)$ What is the braking force at the end of $5$ seconds to bring the car to a stop within one second ?
Name the physical quantities denoted by
$(i)$ The slope of the distance$-$time graph.
$(ii)$ The area under velocity$-$time graph.
$(iii)$ The slope of velocity$-$time graph.
Write true or false for the following statements
A body is said to be at rest, if it does not change its position with respect to the reference point.
If the displacement$-$time graph for a particle is parallel to time axis, what is the velocity of the particle ?
