Frequently Asked Questions
Motion is the change in position of an object with respect to time and a reference point.
An object is said to be at rest if it does not change its position with respect to its surroundings.
Distance is the total path length covered by an object during motion.
Displacement is the shortest straight-line distance between the initial and final positions of an object.
The SI unit for both distance and displacement is metre (m).
Speed is the distance covered by an object per unit time.
Speed = Distance / Time.
Average speed is the total distance traveled divided by total time taken.
Velocity is the rate of change of displacement with respect to time.
The SI unit for both is metre per second (m/s).
Motion in which an object travels equal distances in equal intervals of time is uniform motion.
Motion in which an object covers unequal distances in equal intervals of time is non-uniform motion.
Acceleration is the rate of change of velocity with respect to time.
a = (v - u) / t, where v is final velocity, u is initial velocity, and t is time.
Metre per second squared (m/s²).
When velocity changes equally in equal intervals of time, it is uniform acceleration.
When velocity changes by unequal amounts in equal intervals of time, it is non-uniform acceleration.
Retardation or deceleration is negative acceleration when velocity decreases.
It represents speed (rate of change of distance with time).
It represents acceleration.
It gives the total distance or displacement travelled by the object.
(i) v = u + at, (ii) s = ut + ½at², (iii) v² = u² + 2as.
u = initial velocity, v = final velocity, a = acceleration, s = displacement, t = time.
The equations of motion were formulated using Newton’s laws of motion.
It has uniformly accelerated motion due to gravity.
Acceleration due to gravity, g = 9.8 m/s² downward.
Velocity is a vector quantity as it has both magnitude and direction.
Speed is a scalar quantity because it has only magnitude.
Displacement can be less than or equal to distance but never greater.
Yes, velocity can be negative when direction is taken into account.
It indicates uniform motion.
It represents non-uniform motion.
Instantaneous speed is the speed of an object at a particular moment of time.
A stone tied to a string and rotated in a circle shows uniform circular motion.
Because the direction of velocity changes continuously, causing change in velocity.
It is the acceleration directed towards the center of the circular path.
A quantity having only magnitude is called a scalar quantity.
A quantity having both magnitude and direction is a vector quantity.
Circular motion.
Linear or rectilinear motion.
Motion of an object with respect to another moving or stationary object is relative motion.
It means velocity is constant and the object is in uniform motion.
Average velocity = Total displacement / Total time taken.
It shows the change in velocity of the object.
Metre per second squared (m/s²), representing acceleration.
In a velocity-time graph, uniform acceleration forms a straight inclined line.
The slope is zero because acceleration is zero for uniform velocity.
s = ut + ½at² gives the distance travelled.
It represents uniform motion.
Motion is studied using concepts like distance, displacement, speed, velocity, acceleration, and time graphs.
