When the downward pull of gravity on an object is equal to the upward force of water (buoyancy), the object will float at a certain level in the water. This is known as the object being in equilibrium, where the forces are balanced and there is no net force acting on the object.
The result is friction.
The path that the object takes to either strike the ground or to orbit the body.
The weight reading on a scale measures the downward force exerted by an object due to gravity. The scale registers the force required to support the object's mass against the pull of gravity, which is then displayed as the weight of the object.
The two forces acting on an object that is falling are gravity, which pulls the object downward towards the center of the Earth, and air resistance, which opposes the object's downward motion and slows its fall.
The downward force exerted on an object is caused by gravity (from the Earth). This force is called weight and can be calculated by multiplying the mass of the object by the acceleration due to gravity on Earth (about 9.8).
The upward force on an object is a measure of the force exerted on it in the opposite direction to gravity. It is often called the normal force and counteracts the downward pull of gravity to keep the object from falling through a surface.
When gravity acts on the mass of an object, it causes the object to have weight. Weight is the force of gravity acting on an object's mass, and it gives the object its downward push or pull towards the Earth's center.
Gravity causes a falling object to accelerate towards the ground at a rate of approximately 9.8 m/s^2 (on Earth). This acceleration due to gravity increases the speed of the object as it falls towards the ground.
The strength of the force in each direction between the earth and any mass is called the "weight" of the mass. The force is equal in both directions, which means that the weight of the mass on earth is the same as the earth's weight on the mass. The force acts along the line between the center of the earth and the center of the mass. The direction toward the center of the earth is customarily referred to as the 'down' direction, and toward the center of the mass as the 'up' direction.
