- s
- kg
- m/s
Which among the following is an oscillatory motion?
- Rotation of the earth about its axis.
- Revolution of the moon about the earth.
- To and fro movement of a vibrating string.
- All of these.
The correct relation among the following is
- Speed = Distance × Time
- Speed = Distance / Time
- Speed = Time / Distance
- Speed = 1 / (Distance × Time)

Q- State True or False. If false, correct the statement.
To and fro motion is called oscillatory motion.[True]
Vibratory motion and rotatory motion are periodic motions.[False]
Vehicles moving with varying speeds are said to be in uniform motion.[False]
Robots will replace human in future.[False]
Q- Answer in a word or two.
The force which acts on an object without physical contact……. Gravity
A change in the position of an object with time……. Motion
The motion which repeats itself after a fixed interval of time…….. Periodic
The motion of an object which covers equal distances in equal intervals of time…… Uniform
A machine capable of carrying out a complex series of actions automatically………. Robot
Q- Answer briefly.
Q- Define force.
Force is a push or pull acting on an object due to its interaction with another object or its surroundings.
Q- Name different types of motion based on the path.
Different types of motion based on the path include linear, curvilinear, circular, and zigzag (irregular) motion.
Q- If you are sitting in a moving car, will you be at rest or motion with respect your friend sitting next to you?
You will be in motion with respect to your friend sitting next to you in the moving car.
Q- Rotation of the earth is a periodic motion. Justify.
Rotation of the Earth is periodic because it repeats its motion about its axis in approximately 24 hours, completing one rotation.
Q- Differentiate between rotational and curvilinear motion
Rotational motion involves spinning around an axis, like a spinning top, while curvilinear motion involves movement in a curved path, like a ball thrown in the air.
