When forces act in opposite directions, they are combined by subtracting the smaller force from the larger force. When you add equal forces in the opposite direction, the net force is zero. So the net force on the body is zero when equal and opposite forces act on a body.

When two equal and opposite forces are acting on a moving body, the motion of the body is not affected, it remains unchanged. it is because the net force acting on the object is zero.

if two forces act on an object in the same direction then the net force is equal to the difference between the two forces. 2. if two forces act on an object in the opposite direction then the net force is equal to their addition of forces.

Answer. When two forces act on a body from two opposite directions and their magnitudes are equal,the forces cancel out each other’s effects,thus produ mcing no change in the body.So,the resultant force is zero.

Action-at-a-Distance Forces

• Applied Force.
• Gravitational Force.
• Normal Force.
• Frictional Force.
• Air Resistance Force.
• Tension Force.
• Spring Force.

When two forces are equal and act on an object in opposite directions, they balance each other out. When this happens, there is no change in an object’s motion. the same direction, the two forces are added together. Adding the forces together cause a change in an object’s motion, speed, or direction.

If two forces of the same strength push in opposite directions, they cancel each other out. Many objects have lots of different forces pushing or pulling them all at the same time. If all the forces pushing an object cancel each other out, the object does not move. We call this being balanced.

Force is defined as a push or pull acting on an object. Forces include gravity, friction, and applied force. Force causes changes in the speed or direction of motion. These changes are called acceleration.

In order for there to be continuous motion, there must always be a force acting on it. Why some people say it’s true: Any object which moves eventually comes to stop. Thus, to keep it in motion, a force must be applied.

Work is done when a force moves something through a distance. To do work on the object, the force must act in the same direction as, or opposite the direction of, the object’s displacement.

repulsion. noun. physics an electrical or magnetic force that makes things move away from each other.

In the absence of any forces, no force is required to keep an object moving. An object (such as a ball) tossed in the earth’s atmosphere slows down because of air resistance (a force).

Work is defined as the use of force to move an object in the direction of that force and is equal to the force times the distance the object moved.

When a force acts on an object over a distance, it is said to have done work on the object. Physically, the work done on an object is the change in kinetic energy that that object experiences.

If there is no motion in the direction of the force, then no work is done by that force. Yet you certainly feel like you are doing work if you carry a heavy box. It changes the direction of the motion, but it does no work on the object.

Not all force that is used to move an object does work. For work to be done, the force must be applied in the same direction that the object moves. If a force is applied in a different direction than the object moves, no work is done.

The luggage does not move relative to his body, so no work done. With respect to the ground, height of the staircase is the distance moved (in line with the direction of the force). The Force is gravity, downward. So negative work done by the gravity.

zero velocity

Answer: Yes, an object can have zero velocity and still be accelerating simultaneously. Let us consider an object moving in the forward direction.

So, when velocity is maximum, acceleration is minimum (zero).
