A bee changes its direction again and again, so its movement is irregular (random motion).

When an object stops, its speed becomes zero, so its velocity becomes zero.

Velocity tells how fast an object is moving and in which direction.

Vector quantities need both magnitude and direction for complete description.

A swing moves back and forth about a fixed point, which is vibratory (oscillatory) motion.

Distance has only magnitude and no direction, so it is a scalar quantity.

An upward slope means speed increases as time passes (positive acceleration).

Distance is measured in meters (m) according to the SI system.

For a person standing outside, the passenger is moving because the bus is moving.

Acceleration = (Final velocity – Initial velocity) ÷ Time
= (15 – 5) ÷ 5 = 10 ÷ 5 = 2 m/s².

The slope (steepness) of the distance-time graph tells how fast distance changes, which is speed/velocity.

A running boy is changing his position with time, so he is in motion.

The Earth revolves around the sun in a nearly circular path and repeats this motion every year, making it periodic motion.

A freely falling body accelerates downward due to gravity, so its acceleration is constant.

A downward slope means the speed is decreasing with time.

The slope shows how fast distance changes with time, which is speed.

Velocity is measured in meters per second (m/s).

The area under the graph represents the distance covered by the object.

The blades of a fan rotate around a fixed axis, so it is rotatory motion.

When an object moves from one place to another in a straight path, it is translatory motion.

To decide if something is in rest or motion, we compare it with a reference point (surroundings).

A horizontal line means distance does not change with time, so the object is not moving.

A steeper slope means distance is increasing more quickly, indicating higher speed.

Velocity has both magnitude and direction, so it is a vector quantity.

A curved line shows that distance is not increasing evenly with time, meaning the object has changing speed.

Velocity tells how fast an object moves and in which direction.

A horizontal line means speed does not change with time, so the object moves with constant speed.

Acceleration has both magnitude and direction, so it is a vector quantity.

The area under a velocity-time graph gives the distance traveled by the object.

Zero acceleration means the velocity is not changing; the object moves with constant velocity.

A straight upward line means distance increases at a steady rate, showing constant speed.

Distance is the total path covered, so 3 m + 4 m = 7 m.

Acceleration is measured in meters per second squared (m/s²).

A horizontal line means distance is not changing with time, so the object is at rest.

Distance tells “how much path is covered,” and it has only magnitude, not direction.

Distance is the actual path length covered by an object during motion.

The velocity of a freely falling object increases by 9.8 m/s each second due to acceleration of gravity.

Force has both magnitude and direction, so it is a vector quantity.

Near the Earth's surface, all free-falling objects accelerate downward at about 9.8 m/s².

Gravity accelerates all objects equally, so they fall at the same rate regardless of mass.

Acceleration tells how quickly the velocity of an object changes with time.

An upward sloping line in a velocity-time graph shows that velocity is increasing at a constant rate.

Scalars have magnitude only and no direction.

Displacement is the straight-line distance between starting and ending points in a specific direction.

Velocity = distance ÷ time = 100 ÷ 10 = 10 m/s, and direction is east.

Displacement has both magnitude and direction, so it is a vector quantity.

Displacement is measured in meters (m), the same as distance.

The person returns to the starting point, so the initial and final positions are the same, making displacement zero.

The stone is not changing its position, so it is at rest.

Distance is always positive because it represents the total path covered.

If an object does not change its position with respect to its surroundings, it is considered at rest.

A straight upward line means distance is increasing at a constant rate, showing constant speed.

Because displacement includes direction, it can be positive, zero, or negative depending on the direction of movement.

A curved line shows that speed changes irregularly, meaning non-uniform acceleration.
