What is the shortest distance covered by a moving object from the point of reference in a specified direction?
- Distance
- Uniform speed
- Velocity
- Displacement
- Acceleration
Which of the following is correct about a body moving with variable speed in a straight line?
- The speed of the body is changing.
- The body is travelling with a constant speed, but it is changing direction.
- It covers equal distance in equal intervals of time in a particular direction.
- The speed as well as the direction of the body is changing.
- Acceleration is absent if the body moves in a straight line.
The process in which an object travels in a straight line and its velocity increases or decreases by an equal amount in equal intervals of time is
- decelerated motion
- uniform acceleration
- velocity
- uniform velocity
- rectilinear motion
