What keeps the object remain at rest answer?

What keeps the object remain at rest answer?

Inertia is a force which keeps stationary objects at rest and moving objects in motion at constant velocity. Inertia is a force which brings all objects to a rest position.

What are the 3 laws of motion?

In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.

What causes inertia?

Therefore the cause of Inertia is Resistance, as Inertia is the resistance for any moving or stationary object to change its state of motion, or as again previously stated as "The tendency for motion to remain unchanged".

What is the importance of inertia?

The principle of inertia helps to provide the answer: since we are in motion together with Earth, and our natural tendency is to retain that motion, Earth appears to us to be at rest.

What factors can decide the inertia of a body?

Inertia is that quantity which depends solely upon mass. The more mass, the more inertia. Momentum is another quantity in Physics which depends on both mass and speed. Momentum will be discussed in a later unit.

Do all the bodies have same inertia?

Answer: All bodies does not have same inertia because inertia depends on the mass of the body. For example it is easy to push or pull or stop a empty box or a book but it is not easy to push or pull or stop a car with the same force you used on the book or box.

What is required to cause acceleration?

The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.

Which has more inertia?

The inertia of a body depends on its mass. If an object has more mass it has more inertia. Heavier objects have more inertia than lighter objects. A stone has more inertia than a rubber ball of the same size because it has more than a rubber ball of the same size.

Which has more inertia a man or a child?

So, a man having a higher mass than child will have more inertia. Actually, the intertia depends on the weight of the object. The more the weight, the more will be the inetia, so it depends who weighs more. but it is common sense that man will weigh more, so the man will have more inertia.

Which has more inertia a truck or a scooter?

Inertia is the property of mass. ... Since truck is the heaviest of all the options, therefore, it has the most inertia.

Which has more inertia a bicycle or a car?

The bike has more inertia, as its mass is greater than the mass of the car. The car has more inertia, as its mass is less than the mass of the bike. The bike has more inertia, as its mass is less than the mass of the car.

Which has more inertia a fast bowling ball or a slow bowling ball?

1 Answer. The bowling ball has a higher inertia.

Which vehicle has more inertia?

A bus has more inertia, because it has more mass. So, greater force is needed to change the state of the body of greater mass.

Which has more inertia hammer or feather?

Answer. Inertia depends on the mass of an object. So the hammer will have the greater inertia than that of a feather.

F = ma

Which has more inertia more force to move?

The more mass an object has, the greater its inertia and the more force it takes to change its state of motion. The amount of inertia an object has depends on its mass - which is roughly the amount of material present in the object.

What would happen if you dropped a hammer and feather on the moon?

Astronaut David Scott re-created, in 1971 during the Apollo 15 mission, Galileo's "falling bodies" experiment by dropping a hammer and feather on the moon at the same time. Simply, both fell at the same rate because there was no air resistance.

Who dropped the feather and hammer on moon?

astronaut David Scott

What drops faster a feather or a hammer?

Because the Apollo crew were essentially in a vacuum, there was no air resistance and the feather fell at the same rate as the hammer. This is exactly what Galileo had concluded hundreds of years before: all objects released together fall at the same rate regardless of mass.

Will a feather and a brick?

Galileo discovered that objects that are more dense, or have more mass, fall at a faster rate than less dense objects, due to this air resistance. A feather and brick dropped together. Air resistance causes the feather to fall more slowly.

Why does a hammer hit the ground before a feather?

Gravity accelerates both objects at the same rate, but another factor comes into play: air resistance. The feather is slowed down more by the air and floats down gently, while the hammer crashes straight to the ground.

Do heavier objects hit the ground first?

In other words, if two objects are the same size but one is heavier, the heavier one has greater density than the lighter object. Therefore, when both objects are dropped from the same height and at the same time, the heavier object should hit the ground before the lighter one.

Do things fall slower on moon?

The Moon's surface gravity is about 1/6th as powerful or about 1.

Which will hit the ground first?

This means that if you dropped a basketball and a tennis ball at the same time (from the same height) they will hit the ground at the same time (try it!). Is this true for all objects? If you drop a feather and a rock at the same time, you know the rock will hit the ground first and the feather will fall much slower.

What falls faster a watermelon or an egg?

The correct answer is the last one: the two will hit the ground at the exact same time. This is because gravity accelerates all objects equally, even if one object is heavier than the other. ... The watermelon also has a lower acceleration because it is heavier and the egg the opposite.

Which ball falls faster?

People often believe that the heavier ball will fall more quickly. They think that gravity acts more on a heavier object thus pulling it down faster. In fact, gravity works independently of mass. This means that all objects should fall at the same rate.

Why do balls hit the ground at the same time?

Gravity is the force that causes things to fall to earth. ... Gravity causes everything to fall at the same speed. This is why balls that weigh different amounts hit the ground at the same time.
