What term describes the motion of an object when it moves in a straight line?

Rectilinear motion

Riddle: I can spin and never change my position, moving around a fixed point. What am I?

Circular motion

True or False: An object in oscillatory motion changes its shape as it moves back and forth.

True

Fill in the blank: The motion that repeats itself after a fixed interval of time is called ______.

Periodic motion

Which type of motion occurs when an object covers equal distances in equal intervals of time?

Uniform motion

What is the SI unit of speed?

Metre per second (m/s)

Fill in the blank: When an object moves along a curved path, it is said to be in ______ motion.

Curvilinear

True or False: Non-periodic motion occurs at regular time intervals.

False. Non-periodic motion occurs without fixed intervals of time.

Riddle: I change my shape as I move fast, but my whole body stays in the same place. What type of motion am I?

Vibratory motion

What is the formula for calculating speed?

Speed = Distance covered ÷ Time taken

What is the difference between mass and weight?

Mass is the amount of matter and remains constant, while weight is the force due to gravity and can change.

Fill in the blank: The force with which the earth pulls an object is known as ______.

Weight

Which type of velocity occurs when an object covers unequal distances in equal intervals of time?

Variable velocity

True or False: An object can have a speed but an average velocity of zero if it returns to its starting point.

True

Riddle: I move in a way that's unpredictable, like a kite on a windy day. What type of motion am I in?

Random motion

What type of motion describes an object that moves back and forth along the same path?

Oscillatory motion

Fill in the blank: The total distance covered divided by the total time taken gives us ______ speed.

Average

What is the unit of weight in the SI system?

Newton (N)

When an object is at rest, what can be said about its position relative to its surroundings?

Its position does not change compared to its surroundings.

Which type of motion involves a body moving in a circular path?

Rotatory motion

Riddle: I travel the same distance every second, yet my direction may change. What am I?

An object with variable velocity

What is the condition for uniform velocity?

The object must cover equal distances in equal intervals of time and maintain the same direction.

Fill in the blank: A motion that does not repeat at fixed intervals is called ______ motion.

Non-periodic

True or False: Speed and velocity are the same because both measure how fast something is moving.

False. Speed does not include direction, while velocity does.

What kind of motion does a clock pendulum exhibit?

Oscillatory motion

What is the term for when an object's motion changes from one type to another unexpectedly?

Random motion

Fill in the blank: The amount of matter in an object is referred to as its ______.

Mass

Which type of motion occurs when the motion of an object is not constant and changes over time?

Non-uniform motion

Riddle: I am the force that changes with gravity, yet my mass is always stable. What am I?

Weight

What is the relationship between speed and distance covered over time?

Speed is the rate at which distance is covered over time.

Fill in the blank: A motion where all parts of a body move the same distance at the same time is called ______ motion.

Translatory

True or False: Curvilinear motion occurs only in a straight line.

False. Curvilinear motion occurs along a curved path.

What is the term for the shortest distance from the starting point to the ending point in a specific direction?

Displacement
