Yes. For instance, say a box is sliding at me at some speed. I push back with a force of 25N directly against the path of the box. Suppose that I stop the box after it goes 25m. So, I pushed against the box, or in the negative direction. The displacement was in the positive direction. So, if W=Fs and -25N=F and s=25m, W=Fs=-25N*25m=-625J.
What else can I help you with?
What would happen if you doubled the force acting on a moving object?
Doubling the force acting on a moving object would cause the object to accelerate at a faster rate, leading to an increase in its speed. This is in accordance with Newton's second law of motion, which states that the acceleration of an object is directly proportional to the force acting on it.
Is an object in equilibrium moving?
An object in equilibrium is not moving, as all the forces acting on the object are balanced. If the object were to be in motion, it would no longer be in equilibrium as there would be an unbalanced force acting on it.
Is centripetal force is acting when ab body is moving in stright line?
No, centripetal force is not acting when a body is moving in a straight line. Centripetal force is required to keep an object moving in a curved path.
If the force acting upon an object are balanced then the object Amust not be moving Bmust be miving with constant velocity Cmust not be accelerating Dnone of these?
If the force acting upon an object are balanced then the object must not be accelerating
What is the result of a force acting on a moving object over a period of time?
The result of a force acting on a moving object over time is a change in the object's velocity. This change can be an increase or decrease in speed, a change in direction, or both, depending on the magnitude and direction of the force.
An object moving with a constant speed of 2 net force?
Because F=ma, If an object is moving at a constant velocity(speed), then there can be no net force acting on the object. This means that there is a dispersive force i.e Drag or friction acting on the object equal to 2 but in the opposite direction to motion.
Can an object be moving but still have a net force of zero?
Yes, an object can be moving at a constant velocity (i.e., moving with no acceleration) and have a net force of zero. This occurs when the forces acting on the object are balanced, such as when an object is in equilibrium.
What happen if the force acting on an object moving on a circle remove?
If the force acting on an object moving in a circle is removed, the object will continue to move in a straight line tangent to the circle at the point where the force was removed, due to its inertia. This is governed by Newton's first law of motion.
If there is no force acting on an object it will what?
If there is no force acting on an object, it will remain in its state of motion (either at rest or moving at a constant velocity) according to Newton's first law of motion.
What is the radial force equation used to calculate the force acting on an object moving in a circular path?
The radial force equation used to calculate the force acting on an object moving in a circular path is F m v2 / r, where F is the force, m is the mass of the object, v is the velocity of the object, and r is the radius of the circular path.
What is required to get a stationary object moving?
An outside force is needed. If friction comes into play (which it likely will), the magnitude of the applied force must be greater than the force of friction acting upon the object in order for the object to move. FYI, the force of friction is equal to the coefficient of static friction times the normal force (equal to the weight of the object).
Example of a Force acting on an object but the object isn't moving?
An example of a force acting on an object but the object isn't moving is when you push against a wall. The force you apply with your hands is countered by an equal and opposite force from the wall, resulting in the object (the wall) not moving.
