Which of these two forces are balanced?
Tap to reveal answer
The answer is "up and down" because the forces in the upwards and downwards directions are equal and opposite.
Forces are acting on us and everything around us, at all times! Even when things are not moving, forces are still acting on them. These forces are said to be “balanced” meaning that they are equal and opposite, and have a net value of zero. When an object is in motion, it is being acted on by an “unbalanced” force.
The force of gravity is what holds us down on Earth. The normal force pushes back up against objects in the opposite direction of gravity and keeps things from getting crushed. These are balanced forces.

The answer is "gravity."
Forces are acting on us and everything around us, at all times! Even when things are not moving, forces are still acting on them. These forces are said to be “balanced” meaning that they are equal and opposite, and have a net value of zero. When an object is in motion, it is being acted on by an “unbalanced” force.
The force of gravity is what holds us down on Earth. It acts in the downward direction, or perpendicular to Earth's surface regardless of the placement of the object. The normal force is the force of surfaces that pushes back up against objects in the opposite direction of gravity. Gravity and the normal force are balanced forces if an object is on a surface and not moving in the up or down direction. Forces applied in other directions are usually referred to as "applied forces."

The answer is "the image on the left and possibly the image on the right, but it depends on how hard each of the men are pushing." The image on the left shows unbalanced forces pushing in the leftward direction. The image on the right could be showing unbalanced forces if one of the men is pushing with a stronger force.
Forces are acting on us and everything around us, at all times! Even when things are not moving, forces are still acting on them. These forces are said to be “balanced” meaning that they are equal and opposite, and have a net value of zero. When an object is in motion, it is being acted on by an “unbalanced” force.
The force of gravity is what holds us down on Earth. It acts in the downward direction, or perpendicular to Earth's surface regardless of the placement of the object. The normal force is the force of surfaces that pushes back up against objects in the opposite direction of gravity. Gravity and the normal force are balanced forces if an object is on a surface and not moving in the up or down direction. Forces applied in other directions are usually referred to as "applied forces."
