OK. (All you need here is Fnetx.)bigredd87 said:
Treat m2 and its pulley as one object. I see 3 forces acting on it.
Of course there is an acceleration constraint, which you need to figure out. When m2 drops X distance, how far must m1 move?
You will apply Newton's 2nd law to m2, just like to m1. Yes, a2 is different from a1, but there is a simple relationship.
No. (But the minus sign is good.) Answer my question earlier: When m2 drops X distance, how far must m1 move? (Get a piece of string and figure it out.)bigredd87 said:
The tension will be the same throughout the rope. The only things exerting a force on m2 are: (1) the ropes; (2) gravity.
Newton's Third Law states that for every action, there is an equal and opposite reaction. This means that whenever an object exerts a force on another object, the second object exerts an equal and opposite force back on the first object.
The general equation for Newton's Third Law is FAB = -FBA, where FAB is the force exerted by object A on object B, and FBA is the force exerted by object B on object A. This equation showcases the equal and opposite nature of the forces.
Yes, Newton's Third Law applies to all types of forces, including gravitational, electromagnetic, and contact forces. It is a fundamental principle in physics and applies to all interactions between objects.
Yes, Newton's Third Law can be observed in many everyday situations. For example, when you push a door, the door pushes back on you with an equal force. When you jump, your feet push down on the ground, and the ground pushes back on you, causing you to move upwards.
Newton's Third Law is closely related to the conservation of momentum. Since the forces between two objects are equal and opposite, the momentum gained by one object is equal to the momentum lost by the other object. This ensures that the total momentum of the system remains constant.
