What are two things affected by friction and how does it impact their movement?
Friction affects the movement of objects by creating resistance. Two things affected by friction are the speed of an object and the amount of force needed to move it. Friction can slow down the speed of an object and require more force to overcome, making it harder to move.
How does friction move things?
Friction does not move things. Friction is the force that opposes motion between two objects that are touching. Not enough friction allows for things to move, depending on what kind of friction; the less force it has.
What are the two things that must be present in order for work to be done?
In order for work to be done, two things must be present: force and displacement. Force is applied to an object to move it, causing it to undergo a displacement in the direction of the force. Work is calculated as the product of force and displacement in the direction of the force.
What two things are needed to make electrons move along a wire?
To make electrons move along a wire, a source of electrical voltage (such as a battery or power supply) is needed to provide the push or force for the electrons to move. Additionally, there must be a closed circuit or path for the electrons to flow through, typically provided by a conductor like a metal wire.
What two things are needed to calculate pressure?
To calculate pressure, you need to know the force exerted on a given area and the area over which the force is distributed. Pressure is calculated by dividing the force by the area.
How much force is used to move 100pds on a 2 pulley system?
In a 2-pulley system, the force required to move a 100-pound object would be halved. Therefore, the force needed would be 50 pounds. This is because the weight is distributed between the two sides of the pulley system, reducing the amount of force required to move the object.
Can you measure the force of friction?
Yes, the force of friction can be measured using a spring scale. The force required to overcome friction between two surfaces can be determined by measuring the force needed to move an object along those surfaces. The friction force is proportional to the normal force between the two surfaces.
Is voltage the force that causes motion?
Voltage is the measure of the electric potential difference between two points in a circuit. It is not the force that causes motion directly, but it provides the potential energy needed to move electric charges through a circuit. The motion of electric charges in a circuit is driven by this potential difference, or voltage.
Why atleast two muscles needed to move any joint in the body......?
Two muscles are not needed to move a joint but a bone attached to a joint in 2 opposite directions .
Why does the gravitational force between two objects that are closer together compare to the gravitational force between two objects as they move farther apart?
The gravitational force between two objects increases as they move closer together because the force is inversely proportional to the square of the distance between them. As they move farther apart, the gravitational force decreases because the distance between them increases and the force weakens.
How does the gravitational force between two objects that are close together compare to the gravitational force between two object as they move father apart?
The force is less as they move farther apart, f=k/r2
