Answer :
Answer: 5. inertia
Explanation:
Inertia refers to an object's resistance to changes in its motion, including turning, speeding up, and slowing down.
The remaining and incorrect options are as follows:
- Momentum (option 1) is a property related to a moving object's mass and velocity.
- Force (option 2) is a push or pull acting on an object.
- Energy (option 3) is the ability to do work.
An object's resistance to changes in motion, such as turning, accelerating, or decelerating, is called inertia(5). It is a fundamental property related to the object's mass and is central to Newton's first law of motion.
An object's resistance to turning, speeding up and slowing down is called inertia. Inertia is the property of an object which measures its tendency to resist changes in its state of motion. Newton's first law, often referred to as the law of inertia, states that a body at rest remains at rest, or, if in motion, remains in motion at a constant velocity unless acted on by a net external force. This law implies that an object with more mass has more inertia and consequently, it is harder to change its state of motion.
For example, it is obviously more difficult to change the motion of a large boulder than that of a basketball. Hence, the momentum of a moving object, defined as the product of its mass and velocity (p = mv), is also related to inertia, reflecting the object's resistance to changes in its motion through both its mass and its velocity.
