Blow on it. Pull it with a string. Place it on a downward slope.
When a skydiver is accelerating downward, the forces are unbalanced. The force of gravity acting downward on the skydiver is greater than the air resistance force pushing upward, causing the skydiver to accelerate downward.
After your finger stops pushing, there are two forces acting on the coin: gravity pulling it downward and the force of the table or surface pushing upward to support the coin and prevent it from falling.
The downward push of water is called "buoyancy" or "hydrostatic pressure." This force occurs due to the weight of the water above pushing down on the water below.
The main forces acting on a shuttlecock falling vertically downward through the air are gravity pulling it down and air resistance pushing against its motion. Gravity accelerates the shuttlecock downward while air resistance slows its descent by pushing against its surface. These forces will determine the shuttlecock's acceleration and terminal velocity as it falls.
The force on you, if you are stationary, exactly balances gravity.
3 forces gravity drag lift
When an object is falling toward Earth, the force pushing up on the object is gravity, which is pulling the object downward towards the Earth's center. There is no active force pushing the object up as it falls.
When a rocket lifts off the ground, the upward pushing force (from the engines) is greater than the downward pull of gravity, allowing the rocket to overcome gravity and lift off into the air.
The reaction force to the downward push of Billy's weight on the chair is the upward force of the chair pushing back on him. The downward force of Billy's weight on Earth is countered by the upward force of gravity acting on him.
