Yes, gravity!
Forces acting in opposite directions combine by subtracting the smaller force from the larger force to determine the net force.
The upward force acting on an object is the normal force. It is equal in magnitude, but opposite in direction to the object's weight.
Having no force acting at all, as the forces will cancel each other out. This results in a net force of zero.
The reaction force to the friction acting on the car is the friction force acting on the road. It acts on the car in the opposite direction to the friction force acting on the car.
Yes, a force acting perpendicular to a horizontal force on a body can cancel out the horizontal force if the two forces are equal in magnitude and opposite in direction. This is known as the equilibrium condition, where the net force acting on the body is zero.
The force exerted by a man climbing a mountain is the sum of the force required to overcome gravity acting on his body plus any additional force needed to grip and pull himself up the mountain surface. The force will vary depending on the angle of the slope, the weight of the man, and the surface conditions of the mountain.
Forces acting in opposite directions combine by subtracting the smaller force from the larger force to determine the net force.
Potential & kinetic
Yes, climbing a mountain involves force and motion. The force comes from the muscles exerting effort to move the body upward, and the motion is the act of ascending the mountain as a result of that force.
To calculate the net force when two forces are acting in opposite directions, subtract the smaller force from the larger force. The direction of the net force will be in the direction of the larger force.
The upward force acting on an object is the normal force. It is equal in magnitude, but opposite in direction to the object's weight.
Having no force acting at all, as the forces will cancel each other out. This results in a net force of zero.
In principle, any force acting on an object is unbalanced, UNLESS there is a second force in the opposite direction, acting on the same object.
The static friction force on block 1 is acting in the opposite direction of the force applied to it.
The force in an inflated balloon is exerted outward equally in all directions.
When force arrows are in opposite directions, you subtract the smaller force from the larger force to find the net force acting on the object.
The reaction force to the friction acting on the car is the friction force acting on the road. It acts on the car in the opposite direction to the friction force acting on the car.
