How do you find the work of an object when given the direction of the force the force the mass and the displacement?

You need to know the component of displacement in the direction of the force.
In the simplest model, Work = Force*Displacement (in the direction of the force).
More complicated models will include friction, for which the mass of the object and the coefficient of resistance between the object and the surface are required. You could also include aerodynamic resistance at which stage the calculations get rather complex.

How does the displacement of a falling object change with time?
for a freely falling object displacement(s)=(1/2)gt^2. (g=acceleation due to gravity) if an object is given initial velocity(u) then displacement equation is s=ut+(1/2)gt^2.
How do you find work if only mass and displacement is given?
First Find the Force Acting on Body take a = 9.8m/s F=ma Second Work Done = Force x Displacement Answer will be in Joules
Instantaneous velocity formula?
v = dx/dt (the derivative of 'x' with respect to 't') where 'x' is the displacement of the objectin a given direction, and 't' is time.
How do you calculate net force in the x direction physics when no x value is given and there are push and pull forces in the x direction?
You add all the forces. Not quite sure what you mean with "no x value is given", but if you don't know ANYTHING about the forces, then you can't calculate the net force either.
How do you find the mass of an object given the weight and volume?
If you know the force of gravity then mass = weight/gravitational force. If you don't then you cannot. Knowing the volume is useless.
Which measurement is a vector quantity?
A vector quantity measures the movement of a particular object in a given direction. An example of a vector quantity is velocity.
If the net force on an object is in negative direction what will the direction is the resulting acceleration be?
It would be in the negative direction as well. Newton's Second law states that the acceleration of an object directly depends on the net force given to that object.
How man joules of work are done on an object when a force of 10 N pushes it distance of 10 m?
One data is not given. Is the direction of displacement the same as that of the force? If so then the angle between displacement vector and force vector will be 0 Work done = force vector . displacement vector ( dot product) So W = F s cos @. @ is the angle between force and displacement vectors. In this sum @ = 0, same direction. So work done = 10 x 10 x cos 0 = 100 J
What happens when an unbalanced force is applied to an object at rest?
It moves the object in the direction of the force. If a force is balanced, it means that a force of equal magnitude and opposite direction is acting upon the same object. If there isn't an equal and opposite force acting on an object, it moves it.
How does force affect the motion of an object?
If you apply force to an object, you accelerate it. If you apply the force in the direction that the object is moving, you speed it up. If you apply it in the opposite direction, you slow it down. If you apply the force in another direction than the object is moving in you will change the direction of the objects motion. The amount of acceleration is given by a = F/m where a is acceleration, F is force and m is the mass of the object.
The overall net force acting on an object produces?
in the same direction as the net force, directly proportional to it, and inversely proportional to the object's mass.
Displacement vs. Time?
Displacement over time, or how far an object has moved in a given time, is the definition of speed. The difference between speed and velocity is that velocity has direction.
What are the possible effects of force when an object moving in a straight line is given a push in the opposite direction?
The object is slowed,The object is stopped,The object's motion is reversed.
How do you find overall velocity?
There is average velocity, and there is instantaneous velocity. I don't think "overall velocity" is a concept generally used in physics; please clarify what you mean.
What will the direction of the resulting acceleration be If the net force on an object is in a negative direction?
It would be in the negative direction as well. Newton's Second law states that the acceleration of an object directly depends on the net force given to that object.
What can be determined from a velocity time graph?
The simplest answer is the velocity of an object at a given time. It is also possible to determine the acceleration and displacement - but only in the same direction as the velocity. No information on motion in a transverse direction can be determined.
How does the Centripetal Force work?
The Centripetal Force is the one that pulls an object that travels on a given path about a point in the direction of this point. This force has been stated by Isaac Newton.
