When a parachutist is falling, the forces acting on them are gravity pulling them downward and air resistance pushing against their fall. Gravity is the dominant force causing the parachutist to accelerate towards the ground while air resistance counteracts this force, eventually leading to a terminal velocity where the forces are balanced.
Gravity is pulling the parachutist downwards towards the Earth, while air resistance (or drag) is pushing upwards against the parachutist's fall, slowing down their descent.
When two forces are acting on an object in the same direction, we combine them by adding their magnitudes together to find the net force acting on the object.
When two forces are acting on an object in opposite directions, we combine them by finding the difference between the magnitudes of the two forces. The direction of the resulting force will be in the direction of the larger force.
The forces acting on a stationary boat in still water are gravity acting downwards, buoyancy acting upwards, and drag acting to oppose any external forces like wind or current. These forces are balanced when the boat is stationary.

When the parachutist opens the parachute, the air resistance force will increase. This will reduce the net force acting on the parachutist, causing a decrease in acceleration over time. As the parachute slows the descent, the net force continues to decrease until the parachutist reaches a terminal velocity.
When two forces are acting on an object in opposite directions, we combine them by finding the difference between the magnitudes of the two forces. The direction of the resulting force will be in the direction of the larger force.

A force of 200*sqrt(2) = 282.8427N (to 4 dp) acting at 45 degrees to the two original forces.
Balanced forces acting on an object do not change the object's velocity.

Acting forces refer to the forces that are currently affecting an object or system. These forces can be external, such as gravity or friction, or internal, like tension or compression within a structure. Understanding acting forces is important in analyzing the motion and stability of objects.
