Use balanced forces in a sentence?
When two people are pushing a box from opposite sides with equal force, the box remains stationary due to the balanced forces acting on it.
When forces are acting in the same direction how do you determine the net force or the force that results from their motion?
Whoa! Force doesn't result from the motion of forces. Let's take it slow. When forces are acting in the same direction, the net force is the sum of the individual forces. Four people, all behind a car, pushing it north. Two men pushing with 200 pounds apiece, two women pushing with 100 pounds apiece. The net force on the car is (200 + 200 + 100 + 100) = 600 pounds north.
When several people are pushing on a large rock and it starts to roll what are the forces acting on the rock?
Depends if they are pushing it up hill or down hill, or on flat ground, or off a ledge/ cliff Is the rock round or cube shaped? Assuming the rock is roughly round, and it is up hill and the people pushing it are Disney characters the forces are Gravity,, friction, Sleepy, grumpy, doc, bashful, micky minnie and goofy.
What kind of forces does NOT change the motion of an object?
Equal and opposite forces. Imagine 2 people pushing a car, one at the front and one at the back. If they are both pushing with the same force, the car will not move.
When finding net force why must you kow the directions of the forces acting on an object?
If you want to know the result of two people pushing a car with equal forces, it'sgoing to help you to know whether they're both pushing in the same direction orin opposite directions. And if you need them to move the car, I'm sure you'll knowwhich method you want them to use, and which method you don't want them to use.
When several people are pushing on a large rock and it starts to roll what do you know about the forces acting on the rock?
When several people push on a large rock and it starts to roll, it means that the force applied by the people was greater than the force of friction holding the rock in place. This causes the rock to overcome static friction and start moving due to the net force acting on it. Once in motion, the force of kinetic friction will act to oppose the motion of the rock.
How do you calculate the net force when two people are pushing in the same direction?
You just add the forces in this case.
What are 3 examples of balanced forces?
Tug a war 2 people pushing on a box on each side
Define balanced force?
There's no such thing as one single balanced force. A group of two or more forces are balanced if they all add up to zero. Like if two people are pushing on the same shopping cart ... one in the back pushing it forward, and one on the front pushing it backward. They add up to zero, and the cart acts exactly as if there are no forces on it at all ... it stands still. Those two forces are balanced.
When there are several people acting on an object and it starts to roll what do you know about the forces acting on the rock?
You know that the combined force is enough to overcome the force of friction.
How many different types of forces are there?
If you are referring to the fundamental forces of nature; there are four, being: -Electromagnetism; this is the force responsible for all things involving magnets and electricity. -Gravity; this is the force that causes objects with mass (more correctly energy) to attract each other. It causes things to fall down and is probably the force most people are most familiar with. The last two forces are not generally known because their influences usually are only felt in the world of small things such as atoms, and their influences are only rarely seen in the every day world. -Weak nuclear force; this force governs certain interactions of sub-atomic particles and in particular it is responsible for radioactive decay. -Strong nuclear force; this force works on only a few types of particles; particles which have a color charge. It is, for example, responsible for binding the protons and neutrons together inside an atomic nucleus. Without this force the nucleus would be pushed apart because the protons repel each other electromagnetically.
What happens when forces are going in opposite directions?
Assuming the two forces are acting ON THE SAME OBJECT, you can subtract the two forces, to get the net force. Important: This does not apply to Newton's Third Law, since the forces act on DIFFERENT OBJECTS. I mention this because people tend to get this confused.
