What is the effect of gravity on velocity?
Gravity is a force and any force acting on a body changes its velocity in the direction of the force.
What forces have a negative effect on velocity just list them?
There are two problems with this question.The less obvious one is: What do you mean by "a negative effect" on velocity ?ANY force that acts in the direction opposite to the direction of the velocity willcause the magnitude of velocity to decrease, which in itself is pretty negative.If the force continues to act long enough, it will eventually cause the velocityto reverse its direction, which is about the most negative effect you can haveon velocity.
The tangential velocity of an Earth satellite is its velocity?
parallel to the surface of the Earth
Why does a force of gravity has no effect on horizontal component of velocity?
The force of gravity points towards the center of the earth ... the direction we call "down". The force has no horizontal component, so it can't have any effect on horizontal speed.
What is the effect of a constant force on speed?
A force, applied to an object, will cause an acceleration, that is, a change in velocity. This may be an increase or a decrease in speed, or a change of direction.
What would be the effect on the orbital velocity of satellite if mass of satellite is double?
Its mass won't affect the orbital velocity.
What is the effect of gravity on velocity?
Gravity is a force and any force acting on a body changes its velocity in the direction of the force.
What is the shape of the orbit when the velocity of the satellite is everywhere perpendicular to the force of gravity?
If the velocity of the satellite is always perpendicular to the force of gravity, then the eccentricity of the orbit is zero, and it's perfectly circular.
The force of gravity is responsible for continuously changing the what of a satellite?
Its velocity.
The force of gravity is responsible for changing the what in which a satellite moves?
The force of gravity will change the satellites direction, and therefore its velocity.
What is the effect on force if the velocity changes from 5 mph to 10 miles per hour?
Velocity does not affect force.
Why satellites revolve around your planet when there is only attractive force between them?
velocity of satellite.
Is torque produce in satellite due to gravity?
A satellite small enough to be treated as a point particle. Can earth's gravity exert a torque on a satellite about the earth's center? Torque causes an object to rotate around a specific point. Torque = force * perpendicular distance and Torque = moment of Inertia * angular acceleration. When a satellite is launched, it is forced up to a specific distance from the earth's center and accelerated to a specific velocity parallel to the surface of the earth. The satellite continues moving in circular orbit. The force which causes the satellite to move in a circular path is the gravitational force caused by the mass of the earth, mass of the satellite, and distance from the center of mass of the earth to the center of mass of the satellite. This force causes the direction of the velocity to rotate so it is always tangent to the circle. This force produces the torque which makes causes the satellite to rotate so the direction of its velocity is always perpendicular to the direction of the gravitational force.
Is the critical velocity equal to orbital velocity of satellite?
Balance of force of gravity by centripetal forceYes, for any given orbital radius (r) only one velocity will give stable orbit, this is called the critical velocity.Pick your orbital radius and satellite mass (m)Use Gmm / r2 to calculate gravitational force (f),then find velocity from : v = sq root ( (r * f ) / m)
Why the weight of a satellite and the centripetal force keeping the satellite in orbit is not a valid example of action and reaction to which Newton's Third Law of Motion applies?
First, Newton's Third Law of Motion says that for every action, there is an equal and opposite reaction.In this scenario, the Earth pulls the satellite. The equal and opposite reaction force would be the pull of the satellite on the Earth, not the centripetal force.The Centripetal force is the RESULTANT force on the satellite that accelerates it(although its speed does not change, velocity changes because the satellite changes direction constantly- it moves in a circular path. And for velocity to change, there must be a net force acting on the satellite), and keeps it in orbit. Please post on my message board if you have any other specific questions.
How velocity of an object can affect its work?
work is the product of force and displacement As velocity is rate of change of displacement, so yes, velocity does effect work.
Inward and outward forces when a satellite is orbiting Earth?
GRAVITY!!!!
