Which of the following situations describes inertia?
a. A stationary object tends to resist being moved.
b. A moving object tends to resist a change in speed.
c. A moing object tends to resist a change in direction
d. all of the above
a, b , c , d in other words all of them
All of the above
The correct answer is d. all of the above.
Inertia is the tendency of an object to resist changes in its state of motion. It refers to both stationary and moving objects.
a. A stationary object tends to resist being moved. This means that if an object is at rest, it will resist any attempts to make it move.
b. A moving object tends to resist a change in speed. This means that if an object is already in motion, it will resist any changes to its speed. For example, it requires a force to speed up or slow down a moving car.
c. A moving object tends to resist a change in direction. This means that if an object is already moving in a certain direction, it will resist any changes to its direction. For example, it takes effort to change the course of a moving bicycle.
In summary, inertia manifests itself in all of these situations, as it describes the resistance of an object to changes in its state of motion.
The correct answer is d. all of the above. Inertia is the tendency of an object to resist changes in its state of motion. It is described by all of the given situations.
To understand this concept, we can use Newton's first law of motion. This law states that an object at rest tends to stay at rest, and an object in motion tends to stay in motion with the same speed and direction, unless acted upon by an external force.
Option a. A stationary object tends to resist being moved: This is an example of inertia at play. If an object is stationary, it requires an external force to move it because it tends to resist changes in its state of motion.
Option b. A moving object tends to resist a change in speed: This is also an example of inertia. If an object is already in motion, it resists changes in its speed. For example, it takes force to accelerate or decelerate a moving car.
Option c. A moving object tends to resist a change in direction: This is another manifestation of inertia. Once an object is moving in a particular direction, it tends to keep moving in that direction unless acted upon by an external force. For instance, when a car turns, the passengers in the car can feel a force trying to pull them in the opposite direction of the turn. This force is a result of the object's inertia resisting the change in direction.
In summary, inertia is the property of objects to resist changes in their state of motion. It is described by all of the given situations, making option d the correct answer.
