Rectilinear motion

The unit of linear acceleration is

• 
  

  $kg-m$
  

• $\frac{m}{s}$

• $\frac{m}{s^{2\ }}$

• $\frac{rad}{s^{2\ }}$

A train covers 60 miles between 2 p.m. and 4 p.m. How fast was it going at 3 p.m.?

• 60 mph

• 30 mph

• 40 mph

• 50 mph

The rate of change of velocity is called ___________

• distance

• displacement

• speed

• acceleration

When speed and direction of motion of a body do not change then the body will have:

• uniform velocity

• uniform acceleration

• variable acceleration

• variable velocity

Speed in a given direction is called

• velocity

• acceleration

• distance

• displacement

When we say a body remains in one position for a long time

• motion

• rest

• stationary

• none of the above

The act, process or state of the change in place or position of a body with respect to time and relative to the observer is said to be ____________

• rest

• stationary

• motion

• none of the above

Which velocity is known as "If equal displacement in equal intervals of time is moving"

• average velocity

• instantaneous velocity

• non-uniform velocity

• none of the above

Tripling the speed of a motor car multiplies the distance needed for stopping is

• by 9 times

• by 6 times

• by 3 times

• by 5 times
