Smoke particles from a chimney exhibit :

physics kinematics different types of motion basics of motion motion and reference point

  1. Random or irregular motion

  2. Circular motion only

  3. Linear motion only

  4. Rotational motion only

Show answer
Correct Option: A
Explanation:

Smoke particles from the chimney have velocities in different direction and thus they exhibit random or irregular motion.

A ball lying on the ground does not move on its own because:

physics kinematics motion around us motion and rest moving things around us

  1. it has inertia

  2. it has no energy

  3. it does not want to move

  4. All of the above

Show answer
Correct Option: A
Explanation:

According to Newtons's first law , body remains in its state unless acted by external force. This property of body is termed as Inertia.

Option A is correct.

A tree in a park is in a state of _____with respect to the ground.

physics kinematics motion around us motion and rest moving things around us

  1. rest

  2. motion

  3. data is insufficient

  4. both A and B

Show answer
Correct Option: A
Explanation:

This totally depends on the frame of refrence, any object is relatively at rest or moving.

earth as  frame of refrenece in this case, the tree is at rest.
