What will happen to an object if the frictional force opposing its motion is greater than the force pushing or pulling it forward?
The object accelerates in the direction of the resultant force.
The upward force that fluids exert on all matter is?
If you place a 5-kg cinder block on a tabletop, it just sits there; it doesn't move. Compared to the tabletop, it's velocity is a constant -- zero, in this case. If an object is moving at constant velocity (even zero velocity), we know that the sum of the forces acting upon it is zero. Hence, we can say that the sum of the forces acting upon the block on the table is zero. So, what are those forces? The obvious one is weight, which is the downward force that is the product of the cinder block's mass and the acceleration due to gravity (W = mg). If weight were the only force acting on the block, it would accelerate downward; in other words, it would fall at an increasing rate. But it's not falling; it's sitting there. So, there must be a force acting upon the block in an upward direction and equal in magnitude to its weight. That upward force that exactly balances the block's weight is called the Normal force.
What if your weight is a force acting on the rock what force acts on you?
If you sit on a rock with a downward force of 'W' pounds, then the rock exerts an upward force of 'W' pounds on your derriere. We know that the sum of the forces on the seat of your pants must be zero. Otherwise the pants would be accelerating, either up or down.
Is running a balanced or unbalanced force?
The forces acting on an object, canceling each other out is a balanced force. An unbalanced force is like a woman and a child tugging on a rope, and the woman is winning and pulling the child toward her- that is an example of an unbalanced force. A balanced force is like two children, about of the same height and weight pulling a rope and they are both balanced to each other and no one is winning- it is equal- that is an example of a balanced force.
How is newtons laws of motion used in cheerleading?
Newton's First Law: The person is at rest while she (I'll pretend it's a girl) is on the ground because no net force is acting on her. Then she is thrown in the air by the force of those throwing her- why does she come down? If we assumed that there was no forces acting on her, she would continue rising forever, but since she falls, there must be a force which causes her motion to change (i.e. to slow down and then reverse direction). That force is gravity. Once on the ground again, she is no longer in motion because the downward pull of gravity is balanced by the upward normal force of the ground, and the net effect is zero force. Newton's Second Law: When in the air, the girl is moving initially with upward velocity, but she slows down and then starts to fall. She must be experiencing a downward force, which again is the force of gravity. You know this because she is accelerating downward, so then you can conclude that gravity is acting in a downward direction. Newton's third law: Ask the throwers- do they feel anything when they throw the girl in the air? They definitely feel pressure on their arms/hands as they throw her upward, because as they exert and upward force on her, she exerts a downward force on them equal in magnitude. The harder they throw her, the more the force they feel on themselves.
What is an upward force created by water called?
It's called the buoyant force. Or you would most likely know it as buoyancy.
What is the upward force due to fluid flow around an airplane wing?
Dont know maybe density force.
When 2 birds are pulling on a worm and the worm moves toward the first bird you know that the force is what?
unbalanced force
What is the force of gravity on Saturn compared to the Earth's gravitational force?
hey hey im 3 and to know the answer its 69 percent of earth gravitational force
What will happen to an object if the frictional force opposing its motion is greater than the force pushing or pulling it forward?
The object accelerates in the direction of the resultant force.
Does Neptune have gravitational force?
Neptune is pulling you toward itself right now, even as we speak. Not only that ! You are also pulling Neptune toward you, with exactly the same amount of force. I know you are. The way gravity operates ... there is a force between every two masses in all of Creation. The force is equal on both bodies, and in the direction that moves them toward each other.
How does a fluid encased bubble 'know' which direction is Up?
If the fluid is not turbulent, then the only forces acting on the bubble are vertical ... the downward gravitational force and the upward buoyant force. Whichever force is the stronger one defines the direction in which the bubble must move.
Which force causes a soccer ball to fall to the ground after it has been kicked up in the air?
The force pulling objects back towards the Earth is gravity.

How does tension affect bridges?
Tension: The curve of the arch and its ability to force the presser outward reduces the 'pulling apart' effect on the bottom of the bridge.
Why aship floats on a water?
Because the weight of ship balances the upthrust force , We know that weight always act downward and upthrust force always act upward so we can say that it comes in equillibrium condition . that's why it keeps floating on water..........
