Question

Which of the following definitions defines the kinematics?
1. It is the study of a body at rest or in equilibrium
2. It is the study of a body in motion without considering the cause of motion
3. It is the study of a body in motion taking into consideration the cause of their motion
4. None of the above

Answer 1

Correct Answer - Option 2 : It is the study of a body in motion without considering the cause of motion

Option 2 is correct, i.e. It is the study of a body in motion without considering the cause of motion.

• Statics: It is the study of a body at rest or in equilibrium.
• Kinematics: It is the study of a body in motion without considering the cause of motion.
• Dynamics: It is the study of a body in motion taking into consideration the cause of their motion.

Note:

• Rest: An object is said to be in rest if it does not change its position with respect to its surroundings with the passage of time.
• Motion: An object is said to be in motion if it changes its position with respect to its surroundings with the passage of time.
