Describe the action and reaction force pairs involved when an object falls toward Earth. Ignore the effects of the air resistance,
Earth's gravity acts as the action force on an object which falls toward Earth. There is drag force which acts as reaction force when the object falls
Hope this helps :3
Well, when an object falls toward Earth, there are two action-reaction force pairs at play. First, we have the gravitational force pulling the object downward towards the Earth. This force is exerted by the Earth on the object, and the object exerts an equal but opposite force on the Earth. So, in a way, Earth is really just grabbing objects that try to escape!
Secondly, we have the contact force between the object and the Earth. As the object falls, it experiences a force from the Earth pushing it upward. This force is exerted by the Earth on the object, and again, the object exerts an equal but opposite force on the Earth. It's like the Earth giving the falling object a little "encouragement" to keep coming back.
So, in summary, gravity is pulling the object down while the Earth is pushing the object up. It's like a never-ending back-and-forth game of tug-o-war between the Earth and objects trying to escape its grasp. Luckily for the Earth, it wins every time!
When an object falls toward Earth, there are two action and reaction force pairs involved:
1. Action and Reaction Pair 1:
- Action Force: The gravitational force exerted by Earth on the object.
- Reaction Force: The gravitational force exerted by the object on Earth (also known as the weight of the object). According to Newton's third law of motion, this force is equal in magnitude but opposite in direction to the action force.
2. Action and Reaction Pair 2:
- Action Force: The force the object exerts on the Earth due to its mass and acceleration.
- Reaction Force: The force exerted on the object by Earth (also known as the normal force). This force acts in the opposite direction as the action force, pushing the object.
These action and reaction force pairs are equal in magnitude and opposite in direction according to Newton's third law of motion. They are necessary for the object to fall toward Earth and for Earth to exert the gravitational force on the object.
When an object falls toward Earth, there are two action-reaction force pairs involved. These force pairs are based on Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
1. Action Force: The Earth's gravitational force on the object
Reaction Force: The object's gravitational force on the Earth
The Earth exerts a downward gravitational force on the object, pulling it toward the ground. According to Newton's third law, there is an equal and opposite force acting on the Earth, pulling it toward the object. However, due to the immense difference in mass between the Earth and the falling object, the impact on the Earth's motion is extremely negligible.
2. Action Force: The object's weight or gravitational force
Reaction Force: The contact force exerted by the Earth on the object
As the object falls, it experiences a weight or gravitational force pulling it downward. In response, the Earth exerts an upward contact force on the object. This contact force prevents the object from passing through the Earth's surface and causes it to accelerate downwards.
Overall, these action-reaction force pairs enable the object to accelerate towards the Earth as gravity pulls it downward, while the contact force from the Earth prevents the object from falling through the ground.
