If an object moves in a circular path it goes faster when the radius gets smaller according to the equation of circular motion F=mv^2 /r
The direction of the force that keeps an object moving in a circle is tangential perpendicular to the the radius.
Acceleration = [ V2 / R ]V = speedR = radius of the path
The velocity of an object moving at a constant speed but in a circular motion due to a centripetal force is constantly changing direction (because velocity is a vector with magnitude and direction), and so since the motion of an object moving in a circle is at a tangent to the circle, this object is defined as constantly accelerating towards the centre of the circle. NB: this is at a constant speed (scalar) and with a constant radius of circle of motion
Yes the radius does affect the area of a circle. In fact to find the area of a circle people need to know the radius. The radius is half way between the middle of a circle to any of it's edges. The formula for the area of a circle ispi*radius squaredYou must first find the square of the radius and multiply it by pi(3.14.) For more help go to Wikipedia.com and type circle.
10 cm Cutting out a quarter of the circle doesn't affect the radius, which is half of the diameter.
A flat round object is a circle. Surface area of a circle = pi*radius squared.
none of the above Force centripetal = (mass * velocity^2) ÷ radius More mass , more force needed to keep object in the circle Object going faster, more force needed to keep object in the circle Larger radius, less force needed to keep object in the circle That is why mass and velocity are in the numerator ( multipliers) and Radius is in the denominator ( divider)
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)
Circular motion is due to the direction of a body/particle/object perpendicular to a radius of the circle drawn to the point of location of the object on the circle.
surface area is the area of a 3D object radius is half of the diameter of a circle
I suggest you calculate the total distance travelled (use the formula for the circumference of a circle), then divide this result by the time to get the speed.
The diameter of a circle is twice the radius.The diameter of a circle is twice the radius.The diameter of a circle is twice the radius.The diameter of a circle is twice the radius.
It is the numerical value of the radius - usually of a circular shape - multiplied by itself. It has no particular significance in itself and is a proportion of the surface area of the object. What proportion of the area depends on whether the object is a circle or sphere.That is the same as radius x radius.
the radius of a circle is r
1.7 is a fine number. It can be the radius of a circle.Any number can be the radius of a circle.
Radius of a circle= Perimeter of the circle/2*pi Radius is half the diameter Radius is the length of a straight line from the center point of the circle to the edge of the circle.
The radius of a circle is half the diameter so if the radius of a circle is r, then the diameter is 2r.
Diameter of circle = 2 * Radius of the circle.
The radius of a circle = the diameter of the circle divided by 2
It is the radius of the circle.
no.the radius of a circle is the distance from the middle of the circle to the edges. no.the radius of a circle is the distance from the middle of the circle to the edges.
The radius of a circle is the distance from the centre of the circle to its circumference - which is the outer limit of the circle.
If the radius is two. it won't be a unit circle, a unit circle is defined as a circle with radius one.
