What are 5 examples of unbalanced forces?
Anything that is accelerating or decelerating because it is only balanced when something is moving at a constant speed.
What are examples of balanced force and unbalanced force?
Examples: Balanced: Two kids are playing tug of war. They are both exerting 4 Newtons of force. (Balanced forces=0 Newtons) Unbalanced: Two kids are playing tug of war. One kid is exerting 6 Newtons of force, the other is exerting 7 Newtons of force. (Unbalanced forces=1 or more Newtons difference[7N-6N=1N) Just because the forces are balanced, doesn't mean that they have to be less than the unbalanced forces. N=Newton
A 20 N falling object encounters 4 N of air pressure what is the magnitude of the net force on the object?
The object experiences 20 newtons pulling it down due to gravity. But it also experiences 4 newtons air resistance pushing it up. 20 - 4= 16 newtons net downward force on the object.
How much work does it take to push a ten kg mass with a force of eighty nine newtons horizontally twenty six meters?
If you push 26 meters with a force of 89 newtons, you do (26 x 89) = 2,314 joules of work.It makes no difference what you're pushing, or what it's mass is.
Two forces act on the same object One force is pushing due east with a force of 6 newtons and the other is pushing due north at 8 newtons What is the resulting force?
The magnitude of the resulting force is 10 N. Because the forces are perpendicular, we can use Pythagoras' theorem:FT = SQRT ( F12 + F22 ) where:FT is the total force;F1 is the first force; andF2 is the second forceUsing this equation, we get:FT = SQRT ( 62 + 82 )FT = SQRT ( 36 + 64 )FT = SQRT ( 100 )FT = 10
What is a demonstration of newtons first law?
That you are pushing the earth down while the earth is pushing you up, so you stay where you are.
Two forces act on the same object. One force is pushing due east with a force of 6 newtons and the other is pushing due north at 8 newtons. What is the resulting force?
10 newtons NE. a little more north than east
How can you use a roller skate a sidewalk and watermto demonstrate how rollind friction works?
If you push a rollerskate down the sidewalk and don't keep pushing it, rolling friction will eventually cause it to stop on its own (assuming that the sidewalk is level and not on a hill)
What can you say about an object at rest pulled in opposite directions by unequal forces?
An object at rest pulled in opposite directions by unequal forces will start to move in the direction of the net force. For example, if I have a chair, and I'm pushing with 10 newtons to the right, and my sister is pushing 5 newtons to the left, the net force is 5 newtons to the right. Therefore, I win, and the chair moves to the right, in the direction of the net force.
Which Newtons law of motion can explain what happens when someone pushes a chair across the floor?
It will have no equilibruim and when you are pushing it you are using a force
An 80kilogram skier slides on waxed skis along a horizontal slope of snow at constant velocity while pushing with his poles What is the horizontal component of the force pushing him forward?
40 newtons. give the explanation of this
Use this formula to compute the pressure of air pushing down with force of 25 newtons over an area of 5 meters?
5
What causes big cracks in the sidewalk?
Big cracks in the sidewalk can be caused by a variety of factors, such as tree roots pushing up underneath the concrete, soil erosion beneath the sidewalk, or the natural settling of the ground over time. Changes in temperature, especially freeze-thaw cycles, can also contribute to cracking by expanding and contracting the concrete.
What are 5 examples of unbalanced forces?
Anything that is accelerating or decelerating because it is only balanced when something is moving at a constant speed.
Would it be true to say that objects accelerate when foces are unbalanced?
That is true. According to Newton's first law of motion: "An object at rest tends to stay at rest, of if it is in motion tends to stay in motion with the same speed and in the same direction unless acted upon by a sum of physical forces." So if I'm pushing in one direction with 5 Newtons of force, and you are pushing in the opposite direction with 3 Newtons of force, the object will begin to accelerate towards you. This is also assuming that we either void the static friction, or we are on a frictionless surface.
A sporting example of newtons 2nd law?
Inertia is a sporting example of newton's first law of motion.
What are examples of balanced force and unbalanced force?
Examples: Balanced: Two kids are playing tug of war. They are both exerting 4 Newtons of force. (Balanced forces=0 Newtons) Unbalanced: Two kids are playing tug of war. One kid is exerting 6 Newtons of force, the other is exerting 7 Newtons of force. (Unbalanced forces=1 or more Newtons difference[7N-6N=1N) Just because the forces are balanced, doesn't mean that they have to be less than the unbalanced forces. N=Newton
