What is inertia? Explain inertia of motion.
Answers
Answer:
Newton's first law of motion 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. ... Inertia is the tendency of an object to remain at rest or remain in motion. Inertia is related to an object's mass. Hopes it's helpful to you.
Inertia is the resistance of a body to remain in state of motion or rest even if force is applied on ot.Inertial is due to mass of that object.
detailed:
(Inertia is the resistance of any physical object to any change in its velocity. This includes changes to the object's speed, or direction of motion. An aspect of this property is the tendency of objects to keep moving in a straight line at a constant speed, when no forces act upon them.)
examples
1. A person is pedaling their bike and suddenly hits the front brakes and their body continues to move and they fly over the handle bars.
2. A person is riding a jet ski in a straight line and suddenly turns the handles and their body continues moving in a straight line at the same speed as they are thrown from the jet ski.
3. A car traveling too fast down a road attempts a curve but the friction is not enough to hold the car and the car continues moving straight and goes off the road.
4. If the moon began to move faster in its path around the Earth, it would move too fast to stay in orbit and go hurdling into out space.
INERTIA OF MOTION
Inertia of motion: If a body is in a state of motion, then it will continue to move at the same speed in the same direction unless an external force is applied to change its state.
Examples:
- While sitting in the passenger’s position on a motorcycle, the sudden application of brakes by the driver causes the passenger to experience a push in the forward direction. This is because the passenger is in a state of motion in the forward direction and the inertia of motion always opposes the change in the state of motion.
- When the passenger of a bus attempts to jump out of the moving bus, the inertia of motion causes him or her to fall down or temporarily lose his/her balance. This is because when the passenger jumps, the inertia of motion of the body tends to oppose the change in state of the body (it wants to continue in the state of motion of the bus rather than coming to a state of rest).
