Motion in a Straight Line

The displacement of an object can be:

1. Always positive
2. Always greater than distance
3. Positive, negative, or zero
4. Always equal to distance

If a body moves with constant speed in a straight line, its motion is:

1. Uniform motion
2. Accelerated motion
3. Circular motion
4. Random motion

The motion of a freely falling body is:

1. Uniform velocity motion
2. Uniform acceleration motion
3. Circular motion
4. Simple harmonic motion

A body moving with uniform acceleration covers:

1. Equal distances in equal time intervals
2. Equal velocity in equal time intervals
3. Equal changes in velocity in equal time intervals
4. Zero displacement

The acceleration due to gravity near the Earth's surface is approximately:

1. 5.8 m/s²
2. 9.8 m/s²
3. 12 m/s²
4. 15 m/s²

An object thrown vertically upward has maximum velocity at:

1. Highest point
2. Initial point
3. Middle point
4. It remains constant

The first equation of motion is:

1. s = ut + ½at²
2. v = u + at
3. v² = u² + 2as
4. s = vt

Which of the following is a scalar quantity?

1. Velocity
2. Displacement
3. Acceleration
4. Distance

The area under a velocity-time graph represents:

1. Acceleration
2. Displacement
3. Force
4. Speed only

A car starts from rest and reaches a velocity of 20 m/s in 5 seconds. Its acceleration is:

1. 2 m/s²
2. 4 m/s²
3. 5 m/s²
4. 10 m/s²

The slope of a position-time graph represents:

1. Acceleration
2. Force
3. Velocity
4. Momentum

A body moving with constant velocity has:

1. Increasing acceleration
2. Zero acceleration
3. Constant acceleration
4. Variable speed

The SI unit of acceleration is:

1. m/s
2. m/s²
3. km/h
4. N

The rate of change of displacement with respect to time is called:

1. Acceleration
2. Velocity
3. Speed
4. Momentum
