What is orbital velocities of celestial bodies?
Orbital velocities of celestial bodies are the speeds at which they move around a central object, like a star or planet. These velocities are determined by the gravitational force between the objects and are necessary for maintaining stable orbits. The orbital velocity of a celestial body depends on its distance from the central object and the mass of the central object.
What is the gravitational force between the earth and a body called?
The gravitational force between the Earth and a body is called weight. Weight is the force exerted on an object due to gravity and is directly proportional to the mass of the object.
What is the gravitational force between the Earth and your body called?
Your weight. Weight is the definition of the force between the earth and other objects. Thus you weight is the gravitational force acting on you from the earth.
What is 1st law of motion?
Newtons 1st law states that every body continues to be in its own state of rest or of uniform motion along a straight path unless it is compelled by any external force to change its state. If a force is exerted on a body the body will move but without force it will not move.
What is the pressure of air outside the body called?
The pressure of air outside the body is called atmospheric pressure. It is the force exerted by the weight of the air in the Earth's atmosphere on a surface.
What is the force exerted upwards from the ground?
In mechanics, the force exerted upwards by the surface that a body sits on is equal and opposite to the force exerted downwards by that body and is referred to as the Ground Reaction Force (GRF) or simply Reaction.
What provides the force that causes the centripetal acceleratoin of the satellite in orbit?
The force that provides the centripetal acceleration for a satellite in orbit is the gravitational force between the satellite and the celestial body it is orbiting, such as Earth. This gravitational force acts as the centripetal force that keeps the satellite in its circular path around the celestial body.
What is relative surface gravity?
Relative surface gravity is a measure comparing the force of gravity on one celestial body's surface to that of another celestial body. It takes into account the differences in mass and radius between the two bodies. This comparison helps in understanding the gravitational pull exerted on objects on the surface of different celestial bodies.
What is a measure of gravitational force acting on an object?
The measure of gravitational force acting on an object is its weight, which is the force exerted on the object due to gravity pulling it towards the center of the Earth or another celestial body. It is typically measured in units of force such as newtons or pounds.
A push or pull exerted on one body by another?
The answer is FORCE
What is the force called that gravity is acting on you?
The force exerted by the earth towards itself,known as the gravitational force is called that gravity is acting on you.
Is bouyancy a downward force exerted by a fluid on a body placed in the fluid?
No, buoyancy is an upward force exerted by a fluid on a body placed in the fluid. This force is equal to the weight of the fluid displaced by the body, according to Archimedes' principle.
What is a push or pull exerted in one body by another?
That is force.
Name the two forces acting on a floating boat?
1) FORCE EXERTED BY THE BODY TOWARDS EARTH {WEIGHT} 2) FORCE EXERTED BY WATER ON THE BODY [DUE TO DISPLACED WATER] NOTE:- HERE THERE WILL BE NO VISCOUS FORCE
When a body is placed on a surface it exert a force but the body does not move or fall why?
If the body is not moving or falling when placed on a surface, it means that the force of gravity pulling the body down is balanced by the force exerted by the surface pushing the body up. This balance of forces results in the body remaining stationary.
What is a force that always acts in a direction exerted by a fluid on a body placed in the fluid?
Buoyant force.
What are examples of force being exerted?
Two examples of force being exerted include gravitational and electromagnetic. A body of mass rested on a surface is being held there by the Earth's force of gravity.
