The application of a force through a distance?
Work = Force * displacement if the displacement and the force are parallel - work is positive if force and displacement are in the same direction, negative if they have opposite direction. At an angle Work = Force * displacement * cos(θ) where θ is the angle between the force and displacement vectors.
What part of a force does work when the direction of the force and the direction of motion are not the same?
Force only takes place in the direction of the motion. It cannot be any other way. It could be argued that the action of a cars tyres on the road applies to your question. The car moves forward while the tyres push the earth in the opposite direction. However the tyres are the motion supplying the force and not the car moving in the opposite direction..
What are the3 laws of motion?
1. A still object will remain still until acted upon by an outside force. A moving object will remain moving in the same direction with the same speed until acted upon by an outside force. 2. An object will move in the same direction as the force it was acted on by and will not stop even if the force stops 3. All actions have an equal and opposite reaction. Hopefully this helped
What is the force when two people pull one thing?
The total force depends upon the magnitude and direction of the two forces. -If the two people are pulling with equal forces in opposite directions, then the resulting force=0, because the two forces cancel out. 33 -If the two people pull in the same direction with 3 N of force each, then the resulting force=6 N in whatever direction they are pulling. 3
How does inertia work?
It is exactly the same as momentum and covered by Newton's first law of motion. Inertia is a way of expressing the force required to get an object to move from rest, or the force required to change the velocity or direction of an object in motion. Anything that has mass will have inertia - a "resistance to move or change velocity or direction of motion".
Is the acceleration of an object always in the same direction of the net force?
No, the acceleration of an object is in the direction of the net force applied to it. If the net force is in the same direction as the object's motion, the acceleration will be in the same direction. If the net force is opposite to the object's motion, the acceleration will be in the opposite direction.
How is the direction of force related to the direction of velocity?
The direction of force influences the direction in which an object accelerates or changes its velocity. If the force is applied in the same direction as the velocity, the object speeds up. If the force is applied in the opposite direction, it slows down.
How do we determine the direction of the impulse vector?
The direction of the impulse vector is determined by the direction in which the force is applied to an object. It is always along the line of action of the force. The impulse vector points in the same direction as the force on the object and causes a change in the object's momentum in that direction.
What is the mechanical advantage is a machine that changes only the direction of the applied force?
if only the direction changes,the input force will be the same as the output force.the mechanical advantage will always be 1.
What is the mechanical advantage of a machine that changes only the direction of applied force?
if only the direction changes,the input force will be the same as the output force.the mechanical advantage will always be 1.
What is the relationship between an object's acceleration and the direction of the force on the object?
If an object is increasing in speed, the acceleration is positive and the force is in the direction of travel. If the object is slowing down, the acceleration is negative and the force is acting against the direction of movement.
What is th calculate net force for forces in the same direction?
To calculate the net force for forces in the same direction, simply add the magnitudes of the individual forces together to find the total force acting in that direction. The direction of the net force will be the same as the original forces.
When a body is thrown up the force of gravity goes in which direction?
The force of gravity is always in the same direction ... toward the center of mass of the other mass that's involved ... whether or not the body is in motion, regardless of what direction it may be moving, and regardless of whether or not you throw up.
Can force be negetive?
No, force cannot be negative as it is a vector quantity and is always expressed with both magnitude and direction. In physics, negative force implies force in the opposite direction to a reference axis.
When force and motion are going in the same direction is work being done?
Yes, work is being done when force and motion are going in the same direction. Work is defined as the product of force applied in the direction of motion and the distance over which the force is applied. So, when force and motion are in the same direction, work is being done.
What will happen to an object if a force pushes it in the same direction as it motion?
The object's speed will increase, accelerating in the same direction as the force.
Does friction move in the same direction as or in opposite direction as the object?
The force of friction ALWAYS acts in the direction exactly opposite to the directionin which the object is moving.If the friction force acted in the same direction as the object's motion, then youwould want to have as much friction as possible, because that would help youmove the object with less fuel.
