exactly! And this force is in fact related to the mass. Friction is proportional to mass. The heavier person experience a stronger force (in the opposite direction of the other forces pulling on him). Another possibility would be that they're holding in say a handle in the other hand.Drizzy said:
ohh but what if caleb and emma wiegh the same? then the forces and their friction is going to be equalIncand said:
No, it means that Emma's grip is weaker. There are different forces at play here, doing different things. Her finger was unable to retain the "hook" position against the force applied by both of them pulling (equal opposite forces). Caleb had a stronger "hook" than Emma, but at no time were the normal forces at their join different (Newton's 3rd).Drizzy said:
Well perhaps one of them have shoes with a coefficient of friction. Or has there foot against something stopping them from moving.Drizzy said:
Well that depends, I assumed a rather theoretical scenario where they hold that position with the fingers, just balancing the forces similarly to when pulling on a rope (from my experience this is what physics questions usually try to highlight).gneill said:
Hand muscles.Drizzy said:
1st what are the two interacting objects in the system? Calebs finger and Emma's finger. Anything outside of these two things are not in the discussed system.Drizzy said:
So in this case where the system is just their interlocking hands, does that mean the person with less mass is more likely to accelerate/shift in position since acceleration = force/mass which in this case the third law reaction pair means the magnitude of their forces on each other are the same?osuboone said:
So basically the force with which Caleb's arm is pulling his hand is greater than the force Emma's arm is pulling her hand, causing her hand to shift towards Caleb due to the imbalance of the total net forces acting on each of their hands? Your explanation makes sense with considering that there's also the force of their arms pulling on their hands but it sort of sounded confusing at first.rcgldr said:
Newton's third law of motion states that for every action, there is an equal and opposite reaction. This means that when two objects interact, they exert equal and opposite forces on each other.
Newton's third law can be observed in many everyday situations, such as pushing a door open, kicking a ball, or even walking. In each of these scenarios, the force of the action (push, kick, step) results in an equal and opposite force in the opposite direction (door pushes back, ball bounces back, ground pushes back).
According to Newton's third law, the force exerted by an object is equal to its mass multiplied by its acceleration. This means that if an object exerts a force on another object, the second object will experience the same force in the opposite direction, resulting in acceleration.
Yes, Newton's third law can be applied to non-contact forces, such as magnetic or electrical forces. For example, when two magnets repel each other, the force exerted by one magnet on the other is equal and opposite to the force exerted by the second magnet on the first.
Newton's third law is essential in understanding the motion of objects because it helps us predict how forces will interact with each other. By understanding that every action has an equal and opposite reaction, we can accurately calculate and predict the motion of objects in various situations.
