Two forces acting in the same direction cause the body to speed up (accelerate) if the forces are acting in opposite directions, subtract one from the other. The difference is the net force on the body and will be the direction in which it accelerates. Obviously, if they're the same size and opposite in direction, providing the body is rigid (it doesn't deform, in other words), the stat of motion of the body will stay the same (either at rest or moving at a steady speed in a straight line).

When you add two forces acting on an object, the resulting force is the vector sum of the individual forces. This is known as the principle of superposition. The direction and magnitude of the resulting force depend on the directions and magnitudes of the individual forces.

What happens to forces when they are acting in the same direction?
Two forces acting in the same direction add together. If those two forces are acting on an object, the object will accelerate faster than if there was only one force acting on the object.
What two forces can make an object move?
Two forces that can make an object move are external forces, such as pushing or pulling it, and gravitational forces acting on the object.
When an object is at rest what are the forces acting on it?
When an object is at rest, the forces acting on it are balanced. This means that the forces pushing or pulling in one direction are equal to those pushing or pulling in the opposite direction. The two main forces in play are gravity acting downwards and the normal force from the surface pushing upwards.
When do two forces that are applied to an object reinforce each other?
Two forces applied to an object reinforce each other when they are in the same direction. This means their magnitudes add up to produce a stronger overall force acting on the object.
What are two forces that are always acting on an object?
Two forces that are always acting on an object are gravity, which pulls the object towards the center of the Earth, and normal force, which is the force exerted by a surface to support the weight of an object resting on it.
What happens to forces when they are acting in the same direction?
Two forces acting in the same direction add together. If those two forces are acting on an object, the object will accelerate faster than if there was only one force acting on the object.
If the net force On an an object is zero what do you know about all of the forces acting on the object?
Net force is a combination of all the foces acting on an object.If two forces are acting in the same direction you add the forces to calculate the net force
What are the effects on an object when two or more opposing forces of unequal mangnitudes are simultaneously applied to the object?
If there are two or more unequal forces acting on an object then the object will be acting on the forces. ^_^
What can you say about the forces acting on a stationary object?
A stationary object has balanced forces acting on it. That means the forces pushing or pulling in different directions are equal in magnitude and opposite in direction, resulting in no acceleration or movement of the object.
What are two forces that are always acting on an object?
Two forces that are always acting on an object are gravity, which pulls the object towards the center of the Earth, and normal force, which is the force exerted by a surface to support the weight of an object resting on it.
What causes acceleration. two forces acting opposite each?
Acceleration occurs when there is an imbalance of forces acting on an object. When two forces of equal magnitude act in opposite directions, the net force is non-zero, resulting in acceleration in the direction of the larger force.
What term best describes the forces acting on an object with the net force of zero?
The term that best describes the forces acting on an object with a net force of zero is "equilibrium." In this state, the forces are balanced, resulting in no overall acceleration or change in motion of the object.
The two forces acting on a falling object are gravity and what?
The two forces acting on a falling object are gravity and air resistance. Gravity pulls the object downward, while air resistance acts in the opposite direction to slow down the object as it falls through the air.
When two or more forces are acting on an object in the same direction how do you calculate the net force?
You find the vector sum of all the forces. That is the resultant, or net, force.
What is tension force and compression force?
Tension forces are two forces acting on one object, moving in opposite directions (away from one another) to stretch the object. Compression forces are two forces acting on one object, moving in opposite directions (towards one another) to compress or deform the object.
What happens if the sum of all the forces acting on a moving object is zero?
Then the object will not accelerate (if it is stationary, then it will remain stationary, if it is already moving it will continue to move at the same velocity until a force begins to act on it).
When you lift an object up two forces act on it identify these forces?
When you lift an object up, the two forces acting on it are the force of gravity pulling it down and the force exerted by you to lift it up. The force of gravity is acting downwards on the object, while your force is acting upwards against gravity to lift the object.
