When driving down the road a firefly strikes the windshield of a bus?
While driving down the road, a firefly strikes the windshield of a bus and makes a quite obvious mess in front of the face of the driver. This is a clear case of Newton’s third law of motion. The firefly hit the bus and the bus hits the firefly.
Does Firefly has more mass than windshield?
We can apply our sense to determine whose mass is more, whether the firefly or the windshield. Of course, the firefly has comparatively less mass than the windshield. Hence, the reason is false .
When a firefly hits a bus each of them exerts the same force?
From Newton’s third law of motion, when a firefly hits a bus, each of them exerts the same force. Firefly has less mass as compared to the mass of the windshield. Hence, assertion is true but reason is false.
How does Newton’s third law work?
Newton’s Third Law: Action & Reaction
His third law states that for every action (force) in nature there is an equal and opposite reaction. If object A exerts a force on object B, object B also exerts an equal and opposite force on object A. In other words, forces result from interactions.
Which has greater force the bus or the firefly?
This is a clear case of Newton’s third law of motion. The firefly hit the bus and the bus hits the firefly. Which of the two forces is greater: the force on the firefly or the force on the bus? … Each force is the same size.
What makes a car go forward explain your answer?
Friction is a force that arises when things rub together. The frictional force between the road and tire is what allows the tire to “push” off the road, thus moving the car forward (Newton’s third law — the action is the pushing frictional force, the reaction is the forward movement of the car).
When a firefly hits a bus each of them exerts the same force R Firefly has more mass as compared to the windshield?
Assertion : When a firefly hits a bus, each of them exerts the same force. Reason : Firefly has more mass as compared to the windshield. Ans : (c) Assertion is true but reason is false. 6.
When we sit on a chair your body exerts?
When you sit in your chair, your body exerts a downward force on the chair and the chair exerts an upward force on your body. There are two forces resulting from this interaction – a force on the chair and a force on your body. These two forces are called action and reaction forces.
When we sit on a chair our body exerts a force downwards?
15. Assertion : When we sit on a chair, our body exerts a force downward and that chair needs to exert an equal force upward or the chair will collapse. Reason : The third law says that for every action there is an equal and opposite reaction.
What is the name of the 3rd law of motion?
Newton’s third law: the law of action and reaction
Newton’s third law states that when two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction. The third law is also known as the law of action and reaction.
When we sit on a chair our body exerts a force downward and that chair needs to exert an equal force upward or the chair will collapse?
Since there is contact between the body and and chair, there is another force that the chair exerts on the body which is opposite in direction i.e. upwards and equal in magnitude according to the third law of motion.
Why do astronauts throw things in space assertions?
Assertion : When astronauts throw something in space, that object would continue moving in the same direction and with the same speed. Reason : The acceleration of an object produced by a net applied force is directly related to the magnitude of the force, and inversely related to the mass of the object.
What is Newton’s 4th Law?
Newton’s Fourth Law or Newton’s Law of Gravitation – Two particles of mass M and m are mutually. attracted with equal and opposite forces F and -F according to the following relationship: ^Mm. -lr.: rz. is the distance between the two particles.
On what part of a swimmer’s body does the water’s reaction force push?
For a swimmer moving his arms through water the greatest lift and drag forces are exerted on the part of the arm that moves fastest through the water, which are generally the hand and forearm. The forearm also generates significant propulsive force in the form of drag.
Why does a wall not move when you push on it?
nothing moves. This is because the force you are exerting on the wall is being balanced by the force you are exerting on the floor in the opposite direction.
