It's mass and the net force acting on it
The two properties that determine how strong of a force gravity will exert on two objects are the mass of the objects and the distance between their centers. The greater the mass of the objects, the stronger the gravitational force will be between them. Additionally, the closer the objects are to each other, the stronger the gravitational force will be.
-- the object's mass -- the net force acting on it
Simply note the sum of their masses, and consider them as one object with that mass.If you're talking about the acceleration of gravity, and asking how fast two objects tied together will fall,then none of that matters. Acceleration of a falling object due to gravity is always the same number,called the "acceleration of gravity". It doesn't matter whether the object is heavy, light, big, small, or42 separate objects tied together. Under the influence of gravity, trucks, bricks, books, and feathersall fall with the same acceleration (if air doesn't get in the way).
The force of friction between the two objects decreases their acceleration when they are moving against each other. Friction opposes the motion of the objects and reduces their acceleration by creating a resistive force that acts in the opposite direction to their movement.
The force that decreases the acceleration of two objects moving against each other is frictional force. Friction acts in the opposite direction to the motion of the objects, creating resistance that impedes their movement. It reduces the net force acting on the objects and consequently decreases their acceleration.
The force that decreases the acceleration of two objects moving against each other is the force of friction. Friction acts in the opposite direction to the motion of the objects and reduces their acceleration by creating resistance.
-- As two objects draw closer together, the gravitational force between them increases. -- Acceleration is directly proportional to force. -- So their acceleration toward each other also increases.
The Atwood machine acceleration equation is a (m2 - m1) g / (m1 m2), where a is the acceleration of the system, m1 and m2 are the masses of the two objects on the pulley, and g is the acceleration due to gravity. This equation shows how the acceleration of the system is influenced by the difference in masses of the two objects and the total mass of the system.
acceleration caused by gravity is not the same because it varies from the mass and the distance betwwen the two objects
To calculate the tension between two objects, you can use the formula T mg ma, where T is the tension, m is the mass of the object, g is the acceleration due to gravity, and a is the acceleration of the object.
To determine the relative velocity between two objects, you can subtract the velocity of one object from the velocity of the other object. This will give you the relative velocity between the two objects.
Two factors that determine the strength of friction between two objects is the smoothness of the surfaces in contact, and the weight of the object moving horizontally.
