Whenever the average and instantaneous velocities are equal the body is said to have a:
Correct answer: B. Uniform velocity
- A. Simple velocity
- B. Uniform velocity
- C. Directional velocity
- D. Centripetal velocity
Explanation
Instantaneous velocity can be equal to average velocity when the acceleration is zero or velocity is constant because in this condition all the instantaneous velocities will be equal to each other and also equal to the average velocity. Or distance -time graph will be a straight line whose slope (velocity) is the same at every point .

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.

A bomb is dropped from an airplane moving horizontally with a speed of 200 km/h. If the air resistance is negligible, the bomb will reach the ground in 5 s, the altitude of the plane approximately is: (g = 9.8 m/s2)
The third law of motion given by Newton deals with an action- reaction pair of forces. Consider two bodies: if the action is due to one body, the reaction will be due to:
A particle is travelling along a straight line OX. The distance x (in metre) of the particle from O at a time ′t′ is given by x = 37 +27t - t3 , where 't' is time in seconds. The distance of the particle from O, when it comes to rest is:
