What is the importance of law of inertia?
The law of inertia is more popularly known as Newton's first law of motion. And that simply says that: An object in motion tends to stay in motion or a body at rest tends to stay at rest unless otherwise acted upon by a net force. This is important in day to day life because it says that when things are moving, like you walking or your car rolling, it will take some sort of braking force to stop that motion. Conversely, if you or your car is at rest, the law says you need to exert some force to get walking or put the pedal to the floor to get the car moving. In sum you are exerting forces to stop or start motion of yourself or of objects all the time. And when you do that you are acknowledging the law of inertia.
What is the force that makes the earth move?
If an object is moving initially, then no force is needed to keep it moving.The earth formed out of clouds of material that revolved around the young sun shortly after its birth.Since the earth was in motion as it formed, and there's nothing to stop it, it continues in motion.It's true that a force is required to CHANGE the speed or direction of an object's motion. The earth's directionof motion is constantly changing ... and it winds up traveling a path around the sun that's very nearly circular.The force that accomplishes that constant 'bending' of the earth's motion is the force of gravitation that drawsthe earth and sun toward each other.
Explain why friction changes the velocity of objects and why friction can make observing newton's first law of motion difficult?
Friction made it difficult to discover newton's first law because under the law an object in motion will remain in motion at a constant velocity unless acted upon by an external force. Friction is an external force that slows objects in motion due to air friction (drag) and rolling resistance, making it appear as though this law is untrue.
Can something stop the US Air Force?
No. Nothing can stop the United States Air Force. The United States Air Force is one of the most powerful air arm in the World. Nothing can stop the US Air Force.
What are the forces around you?
Forces are pushes or pulls. They can start objects moving, they can stop,speed up, slow down, or change the direction of moving objects. They can lift things, or cause them to turn, bend or twist. They can also prevent motion; eg. a handbrake on a car stops it from rolling down the hill.
What causes objects in motion to stop?
FRiction
The unbalanced force that stops almost everything is?
The force you are referring to is friction. Friction opposes motion and causes objects to slow down and eventually come to a stop.
What force causes the car to stop by opposing the motion of the car?
The force that causes the car to stop by opposing its motion is friction. Friction occurs between the tires of the car and the road surface, creating a force that resists the motion of the car, ultimately bringing it to a stop.
What is a common unbalanced force acting on objects in motion?
Friction
The force that rubs things away?
Friction is the force that resists the motion of one object moving relative to another. It causes objects to slow down and eventually come to a stop when they are in contact with each other.
What causes objects to move or moveing objects to stop moveing?
Motion can only be changed when a force is applied. This may be due to an acceleration field (such as gravity) and the mass of the object, or the force may be applied directly and externally by a second object.
What force acts to slow down and eventually stop the movement of all objects?
The force that acts to slow down and eventually stop the movement of all objects is friction. Friction is a force that opposes the motion of objects when they come into contact with each other.
How does friction always effect the motion of objects?
Friction always opposes the motion of objects by creating a force that acts in the opposite direction of the object's motion. This force resists the movement of the object, causing it to slow down or stop. Though friction can sometimes be reduced, it will always be present to some degree and affect the motion of objects.
How do force and motion relate?
Force is any interaction that, when unopposed, will change the motion of an object. Force can cause an object to accelerate, decelerate, stop, or change direction. Essentially, force and motion are directly related, as force is what causes changes in the motion of an object.
Why newton's first law of motion can be difficult to observe in moving objects?
Because you never see objects moving forever. If you roll a ball across a table then a force causes it slow down and stop called friction.
Why are heavier objects harder to start or stop moving?
Heavier objects have more inertia, which means they resist changes in their motion. More force is needed to start or stop the motion of a heavier object compared to a lighter one.
Are force and motion the same or different?
Force and motion are different concepts. Force is a push or pull acting on an object, while motion is the change in position of an object over time. Forces can cause objects to move, change direction, or stop moving.
