What is the actual path length traveled by an object called?

Distance

True or False: Displacement can be zero even if distance is not zero.

True. When initial and final positions are the same, displacement is zero.

Fill in the blank: _____ is a vector quantity requiring both magnitude and direction.

Displacement

Which type of motion involves equal distances in equal time intervals?
A) Non-uniform motion
B) Uniform motion
C) Circular motion
D) Oscillatory motion

B) Uniform motion

What happens to velocity direction in uniform circular motion?

It changes continuously while speed remains constant

A car travels 30 km north, then 40 km east. What is displacement magnitude?

50 km (using Pythagorean theorem: √(30² + 40²) = 50)

True or False: Average speed equals average velocity magnitude for straight-line motion in one direction.

True. When object doesn't change direction, distance equals displacement magnitude.

What does the slope of a position-time graph represent?

Average velocity

Fill in the blank: Average acceleration = change in _____ divided by time interval.

Velocity

Which equation relates velocity, initial velocity, acceleration and time?
A) s = ut + ½at²
B) v² = u² + 2as
C) v = u + at
D) a = v/t

C) v = u + at

What is the SI unit of acceleration?

M/s² or m s⁻²

True or False: An object moving at constant high speed has zero acceleration.

True. Acceleration depends on velocity change, not speed magnitude.

What does the area under a velocity-time graph represent?

Displacement

A ball falls from rest with acceleration 10 m/s². What's velocity after 3 seconds?

30 m/s (using v = u + at = 0 + 10×3)

Fill in the blank: For one complete circular revolution, displacement equals _____.

Zero

Which graph has steeper slope indicating higher velocity?
A) Flatter position-time graph
B) Steeper position-time graph
C) Horizontal velocity-time graph
D) Curved acceleration-time graph

B) Steeper position-time graph

What causes acceleration in uniform circular motion despite constant speed?

Continuous change in velocity direction

True or False: Distance is always greater than or equal to displacement magnitude.

True. Distance is actual path length; displacement is shortest distance.

A car decelerates from 20 m/s to rest in 4 seconds. Calculate acceleration.

-5 m/s² (using a = (v-u)/t = (0-20)/4 = -5)

Fill in the blank: Kinematic equations apply only when acceleration is _____.

Constant

What determines stopping distance of a vehicle?
A) Only braking capacity
B) Only initial velocity
C) Velocity, road surface, braking capacity, reaction time
D) Only road conditions

C) Velocity, road surface, braking capacity, reaction time

Which equation helps find displacement without knowing final velocity?

S = ut + ½at²

True or False: Velocity and speed have the same SI unit.

True. Both are measured in m/s or m s⁻¹.

An object travels 100m in 20s, then returns in 30s. What's average speed?

4 m/s (total distance 200m ÷ total time 50s)

Fill in the blank: Motion in a plane is also called _____ dimensional motion.

Two

What happens when a marble rolling in a ring is suddenly released?

It moves in straight line tangent to the circle

Which kinematic equation doesn't involve time?
A) v = u + at
B) s = ut + ½at²
C) v² = u² + 2as
D) None of these

C) v² = u² + 2as

True or False: Negative acceleration always means the object is slowing down.

False. Negative acceleration means acceleration opposes chosen positive direction.

Calculate distance when object accelerates from rest at 2 m/s² for 5 seconds.

25 m (using s = ut + ½at² = 0 + ½×2×25)
