The property of a body by which it resists any change in the state of rest or uniform motion in a straight line is called inertia. It is described by Newton’s first law of motion, often summarized as “an object ...

Swimming in water is possible due to Newton’s third law of motion. This law states that for every action, there is an equal and opposite reaction. The action of pushing against the water with hands and feet results in a ...
For every action, there is a reaction in equal and opposite direction. This is called Newton’s third law of motion. It states that when one object exerts a force on another object, the second object exerts an equal and opposite ...
According to Newton’s third law of motion, the forces related to action and reaction can be applied on different objects. This law states that for every action, there is an equal and opposite reaction, which means the forces act on ...
The acceleration produced in a body by an unbalanced force is directly proportional to the force. This relationship is described by Newton’s second law of motion, which states that acceleration is directly proportional to the force applied and inversely proportional ...
The statement describes Newton’s first law of motion. According to this law, an object remains at rest or continues to move at a constant velocity in a straight line unless acted upon by an external force. Therefore, the correct answer ...
The difference between the mass and weight of a body is that mass remains constant, while weight is variable. Mass represents the amount of matter in an object, which does not change, while weight depends on gravitational force and varies ...
If the velocity of a moving object is doubled, its kinetic energy quadruples. This relationship is governed by the kinetic energy formula, which is proportional to the square of the velocity. Therefore, the correct answer is [C] Kinetic energy quadruples.
When a boy sits on a rotating round table, the angular velocity will decrease. This decrease occurs due to the conservation of angular momentum. The addition of mass increases the moment of inertia, causing a reduction in angular velocity to ...
When the girl stands up from swinging in a sitting position, the time period of the oscillations will increase. This change occurs because her center of mass rises, altering the swing’s dynamics. As a result, the swing takes longer to ...
