What is the definition of velocity?

Rate of change of position with respect to time
Distance covered per unit time
Speed without direction
Change in acceleration

Which of the following is a vector quantity?

Velocity
Speed
Distance
Time

If an object moves with constant velocity, what can be said about its acceleration?

Its acceleration is zero
Its acceleration is constant
It accelerates increasingly
Cannot be determined

The slope of a position-time graph gives:

Velocity
Acceleration
Distance
Time

The area under a velocity-time graph represents:

Displacement
Speed
Acceleration
Time

Acceleration is defined as:

Rate of change of velocity with respect to time
Rate of change of displacement
Distance traveled per unit time
Speed in a given direction

If a car accelerates from 0 to 20 m/s in 5 seconds, what is its acceleration?

4 m/s^2
5 m/s^2
20 m/s^2
0.25 m/s^2

Displacement differs from distance because:

Displacement includes direction
Distance measures speed
Displacement is always positive
Distance has magnitude and direction

Uniformly accelerated motion means:

Acceleration is constant
Velocity is zero
Speed varies randomly
Displacement is zero

Which equation relates final velocity, initial velocity, acceleration, and displacement?

v^2 = u^2 + 2as
v = u + at^2
s = ut^2 + 1/2at^2
v = s/t
