My 7 year old child asked me today about magnetism. His question was "Does the magnet pull in the paper clip, or does the paper clip pull the magnet" . He then said to me "If i tie a rope to a tree and pull on the rope with enough force I will be dragged to the tree, so how do you know which...
I have a question, let’s say I’m holding a long piece of wood such as. 1’ x 6’ plank and I’m rotating it in a circle by spinning around with my hands extended, I suddenly let go, what happens to the velocity of the wood since every point on the wood that is a different distance from the center...
It’s also hard to visually make sense of force because force isn’t something we can see it’s something we can feel. We can’t see something is heavy. So trying to make sense visually on paper is hard because I have no idea really what force is visually explained. So it seems almost impossible to...
Since force is motionless meaning if I am traveling at at a slope of x:3 y:-4 into a plane once I make contact with that plane and create a force there is no distance traveled as in the force going to the right 3 units and down 4 units. What I am saying is how do the lengths ratios (distance)...
How is it verified and why does it work for force? A triangle shows distance I guess we are Just suppose to be like blind sheep and believe everything our physics books tell us since no one has a valid explanation of how / why the distance ratios can transfer to force ratios
Hi I am studying force components on a inclined plane. I understand the concept of breaking vectors into X , Y Components relative to the horizontal plane however what I can't seem to make sense of is how the ratios of a triangle and the main input force being the hypotenuse of the triangle...
I have a question. What will happen if you have a long object let’s say a person was lassoed by their feet and spun around by a super strong machine or person. Since the persons head of who is being spun is moving at a much faster tangential velocity then let’s say their feet. If the rope is cut...
I have a question about work. If Newtons 3rd law of motion states there is an equal and opposite reaction for any force. Now if for example I apply 500 Newtons of force on my dresser and move it 5 meters I used 2500 joules of energy. Now because the dresser is equally putting that much force...
Hi just have a basic question. Just went to the local fair yesterday and road the Gravitron ride. The ride that sucks you to the walls. I became curious on the physics that cause you to get stuck to the wall so I have been researching centripetal force. Now it seems that the seats are...
Question that’s been boggling my mind. If you have a 1 ft torque wrench and your tightening your wheels on you Car and apply a force of 70 pounds 1 ft from the nut I’m applying 70 pounds of downward force on the nut but applying a much larger torque to the nut. Now if I apply a 70 lb force 3”...
Hello all,
Just wondering if there is a mathematical formula that calculates the maximum rpm. If I have a fan that puts out 3 pounds of rotational force at stall speed(completely still) at the end point of a 1.5 ft blade what would be the maximum rpm of this fan with the blade attached. What...
So I understand the relationship between mass x acceleration=force but all that relationship tells me is "Whatever the force is to accelerate a given mass at a specific unit of acceleration = units of force, and we just accept whatever the unit of force is. example 1/ms² x 1 kg mass = 1 N...
just wondering why no one has made a camera that can truly capture an instant of time. I'm talking about an instant which is defined as an instantaneous moment that has 0 duration. Why do all cameras have shutters that open for a specified amount of time instead of just capturing a true...
