Did you exert a force to keep the stone moving in a circle?
Yes, to keep an object moving in a circle, a force must be exerted towards the center of the circle. This is known as centripetal force.
When moving in a circle an object always wants to keep moving in a straight line due to?
inertia
What provides the centripetal force needed to keep the stopper moving in a circle?
The tension in the string provides the centripetal force needed to keep the stopper moving in a circle. This tension pulls the stopper towards the center of the circle, maintaining the circular motion.
What provides the forces that causes the centripetal acceleration of a satellite in orbit?
When something is moving in circular motion there are two forces that concern the object, excluding forces affecting the motion of the object going around the circle as these would not make the acceleration constant, the force that pushes it inwards towards the centre of circle and the force that pushes it outwards towards the circle, the gravitational field from the mass at the centre of the orbit will provide the inward force, pulling the object inwards towards the centre, and the weight of the satellite will push it outwards towards the edge of the circle Correction- there is only one force- gravity- acting on a satellite in orbit. If it weren't for gravity, the satellite would fly off in a straight line. There is no outward pushing force.
When you observe an object moving in a circle what can you infer about the net force acting on it?
The net force is directed toward the center of the circular path that the object is moving along, and it has a magnitude equal to the velocity squared times mass divided by the radius of the path. (mv^2/r)
What is another word for an artificial object moving around the earth?
Satellite
If an object is moving in a circle with a constant speed Its acceleration is constant in what?
If an object is moving in a circle with a constant speed, its acceleration is directed towards the center of the circle and is constant in magnitude. This acceleration is called centripetal acceleration and is required to keep the object moving in a circular path.
How can a body be accelerating when moving at constant speed?
A body is being accelerated if its speed OR direction are changing.A satellite in a perfectly circular orbit around the earth ... like a TV satellite ... is moving at constant speed. But, technically, since its direction is always changing, to keep it on a circle, it's experiencing constant acceleration.
How does a centripetal force keep an object moving in a circle?
A centripetal force acts towards the center of the circle, continually changing the object's direction towards the center. This force prevents the object from moving in a straight line and keeps it moving in a circular path.
Why doesn't a satellite need fuel to keep moving?
A satellite in orbit maintains its speed and trajectory due to its momentum and gravitational forces. Once in space, where there is no air resistance to slow it down, a satellite can orbit without the need for additional fuel. Exceptions include satellites that require positional adjustments or propulsion for specific maneuvers.
The inward force needed to keep an object moving in a circle?
The force that keeps objects moving in a circle is known as the centripetal force, which acts towards the center. The velocity of the object moving in a circle will be tangential to the circle.
Can a satellite orbit the Arctic Circle?
Yes
