A 250 g yoyo is swung on the end of a 50 cm string at a constant speed of 4 ms The centripetal force acting on the yoyo is?
MOMO2591
It's either the axiom or the velocity of the swinging motion.....of course the yoyo must be goin in a full loop or circle (not the yoyo spinning itself) to act on it... other than that im almost 80% sure im right.

What keeps the force of a ball on a string moving in a circle?
No. The force keeping a ball on a string moving in a circle is centripetal force, i.e. force pulling the ball to the center of the circle.
What is the origin of centripetal force?
Centripetal force is the resultant force acting towards the centre of orbit of an object undergoing uniform circular motion.
In centripetal force what is the relationship between v and f if r is kept constant?
Centripetal force has the following formula: Fcentripetal = m times V2/r What that says is that for a constant r in an example, the Fcentripetal is proportional to V2. The centripetal force is proportional to the square of the velocity of the object.
What provides the centripetal force needed to keep the stopper moving in a circle?
The string
What is the manifestation of centripetal force in a stone tied to a string and whirled horizontally?
The circular path that the stone follows is. It takes centripetal force to move any mass in a circular path.
What provides the centripetal force that keeps objects in orbit?
Centripetal force wants to move something towards the centre. So in a satellites case that would be the Gravity of the Earth. If you had a rock tied to a string you were spinning around, the Centripetal Force would be the tension in the string acting towards the centre.
What is A 0.25 kg stone tied to a 0.5 m string whirls at a speed of 4 m s What is the centripetal acceleration acting on the stone?
Centripetal acceleration = V2/R = (4)2/(0.5) = 32 meters/sec2The centripetal acceleration doesn't depend on the stone's mass.(The centripetal force does.)The centripetal acceleration doesn't "act on" the stone.(The centripetal force does.)The centripetal force acting on the stone is F = M A = (0.25) (32) = 8 newtons.
What would happen to an object if the centripetal force acting on it stops?
Picture a ball on a string being whirled about the head of an experimenter. If the string breaks, the centripetal force disappears. The ball leaves on a tangent path form its (previous) circular path. Yes, it's that simple. The string provided centripetal force, by virtue of its tensile strength, to the ball to keep that ball moving in a circle. When the string broke, there was no force left to accelerate the ball "in" and keep it moving in an arc.
What is centripetal force and centrifugal force examples in dailylife?
Centripetal force is the force necessary to apply to an object to get it to orbit; like spinning a rock on a string. It you are holding on to the string, you will feel a centrifugal force.
What keeps the force of a ball on a string moving in a circle?
No. The force keeping a ball on a string moving in a circle is centripetal force, i.e. force pulling the ball to the center of the circle.
What is the origin of centripetal force?
Centripetal force is the resultant force acting towards the centre of orbit of an object undergoing uniform circular motion.
What is the formula to find centripetal force?
Centripetal force is always directed towards the center of the circle of motion that an object is traveling in.
What effects gravity and centripetal combined on the same orbiting path?
I'm not sure exactly what you are asking, but centripetal force is just a name given to any force that causes circular motion. Swing a rock on the end of a string and the string tension is the centripetal force. Drive a car around a flat circular track and the friction between the tires and the road is the centripetal force. Put a satellite in orbit and gravity is the centripetal force.
The force keeping a ball on a string moving in a circle is called what?
centripetal
What happens to the motion of an object tied with a string being whirled in absence of gravitation when the centripetal force acting on it stops and the object is still tied with the string?
the object will go in its tangential direction of that instant. centripetal force pulls the object toward its rotational axis, so if there is no force pulling it inward; inertia will make the object go in the direction it "wants to go" aka- its tangential direction
In centripetal force what is the relationship between v and f if r is kept constant?
Centripetal force has the following formula: Fcentripetal = m times V2/r What that says is that for a constant r in an example, the Fcentripetal is proportional to V2. The centripetal force is proportional to the square of the velocity of the object.
