Choose the correct alternative. |
The acceleration of a moving particle is always in the direction of its velocity Velocity and acceleration vectors of a moving particle may have any angle between 0 and 360 between them Velocity and acceleration vectors of a moving particle may have any angle between 0 and 180 between them If the acceleration vector is always perpendicular to the velocity vector of a moving particle, the velocity vector does not change |
Velocity and acceleration vectors of a moving particle may have any angle between 0 and 180 between them |
In circular motion, acceleration vector is perpendicular to velocity and velocity is also changing. Now acceleration and velocity can have any angle between them. |
