Bees flying is an example of random motion.

Vibratory motion is also termed as ____ motion.

Correct! Wrong!

Vibratory motion is also termed as oscillatory motion.

Motion of a swing is an example of ____ motion.

Correct! Wrong!

Motion of a swing is an example of oscillatory motion. The to and fro motion of an object about a fixed position is known as oscillatory motion.

The rate of displacement is ____.

Correct! Wrong!

Rate of change of distance is speed while, rate of displacement is velocity.

A body moves from A to B with a velocity of 20 m/s and comes back from B to A with a velocity of 30 m/s. The average velocity of the body during the whole journey is ____ m/s.

Correct! Wrong!

Average velocity is the rate of net displacement during the whole journey. As initial and final points are same, displacement is zero. Hence, average velocity of the body is zero.

If you stand at the centre of a circular track and watch athletes run around it, their distance from you remains the same while running, that means they are at rest.

Correct! Wrong!

Though the distance is the same their position is changing continuously with time. Hence the athletes running in a circular track are in motion.

A ball rolling down an incline plane has ____ and ____motion.

Correct! Wrong!

A ball rolling down an incline plane has rectilinear and rotatory motion

The oscillations made by a pendulum is an example of ____ motion.

Correct! Wrong!

The oscillations made by a pendulum are an example of vibratory motion.

Oscillatory motion is the ____ motion of a body about its position of rest.

Correct! Wrong!

Oscillatory motion is the periodic motion of a body about its position of rest.

Whirling of a stone along a circular path is called ____.

Correct! Wrong!

Whirling of a stone tied to a string is an example of circular motion. The movement of a body along a circular path is called circular motion.

SI unit for the average velocity is ____.

Correct! Wrong!

Average velocity is defined as the ratio of total displacement and total time taken. SI unit of average velocity is m/s.

If the position of a body remains the same with time, it is said to be ____.

Correct! Wrong!

If the position of a body remains the same with time, it is said to be at rest.

The trees appear to be moving for a person ____.

Correct! Wrong!

The trees appear to be moving for a person sitting near a window in a moving train.

The motion of a cyclist around a circular track is a ____ motion.

Correct! Wrong!

The motion of a cyclist around a circular track is a circular motion.

____ is an example of rotational motion.

Correct! Wrong!

Motion of a fan is an example of rotational motion.

Motion of a child in a swing is ____ motion.

Correct! Wrong!

Motion of a child on swing is an oscillatory motion.

The wheel of a bicycle in motion is in ____.

Correct! Wrong!

The wheel of a bicycle in motion is in rotational motion.

Which of the following is incorrect?

Correct! Wrong!

As speed has only magnitude but no direction, it is a scalar quantity. Velocity, retardation, acceleration due to gravity and displacement has both direction as well as magnitude. Hence, they are vectors.

A car moving along a straight road is in ____ motion.

Correct! Wrong!

A car moving along a straight road is in rectilinear motion.

Which of the following is not a periodic motion?

Correct! Wrong!

The motion of a cyclist along a straight road is not a periodic motion.

If a body moves along a curved line, the motion is ____.

Correct! Wrong!

If a body moves along a curved line, the motion is curvilinear.

Which of the following is in motion?

Correct! Wrong!

Flying bird is in motion.

Pick the odd one out from the following.

Correct! Wrong!

Car moving along a straight path is the odd one here as it is in rectilinear motion while the other three are in rotational motion.

The motion of a baseball hit into the air, a car negotiating a bend or a man walking along a curved path are examples of ____ motion.

Correct! Wrong!

The motion of a baseball hit into the air, a car negotiating a bend or a man walking along a curved path are examples of curvilinear motion.

Unit of acceleration is m/s2.

Correct! Wrong!

Unit of acceleration is m/s2.
