What does the path of an object look like when it is in uniform motion?
An object having uniform motion has a straight line path.
The speed-time graph for a car is shown is Fig.
$(a)$ Find how far does the car travel in the first $4,sec$. Shade the area on the graph that represents the distance travelled by the car during the period.
$(b)$ Which part of the graph represents uniform motion of the car ?
A stone is thrown in a vertically upward direction with a velocity of $5\, m s^{-1}$. If the acceleration of the stone during its motion is $10\, m s^{-2}$ in the downward direction, what will be the height attained by the stone and how much time will it take to reach there ?
What is the nature of the distance-time graphs for uniform and non-uniform motion of an object ?
What can you say about the motion of an object if its speedtime graph is a straight line parallel to the time axis ?
State which of the following situations are possible and give an example for each of these:
$(a)$ an object with a constant acceleration but with zero velocity
$(b)$ an object moving with an acceleration but with uniform speed.
$(c)$ an object moving in a certain direction with an acceleration in the perpendicular direction.
