If the acceleration of a particle is constant in magnitude but not in direction, what type of path is followed by the particle ?
The particle follows a circular path.
Why does (second)$^{2}$ occur in the unit of acceleration ?
A girl walks along a straight path to drop a letter in the letterbox and comes back to her initial position. Her displacement-time graph is shown in Fig. Plot a velocity – time graph for the same.
A body is thrown vertically upward with velocity $u$, the greatest height $h$ to which it will rise is,
A car travels $100\, km$ east and then $100 \,km$ south. Finally, it comes back to the starting point by the south-east route. Throughout the journey the speed is constant at $60\, km h ^{-1}$. The average velocity for the whole journey if time taken is $3.3$ hours is
What is the average velocity of a particle when it returns to the starting point ? Can its average speed be zero ?
Confusing about what to choose? Our team will schedule a demo shortly.
