When the radius and the mass of the rotating object are held constant does increasing the period increase or decrease the centripetal force?
f = m * ( v^2 / r )
.
if the mass (m) and circular velocity (v) remain constant, increasing the radius (r) will decrease the force (f), and vice versa.
.
example:
10 kg mass, 10 m/s circular velocity, radius 1 m
force = 1 000 n
.
double the (1 m) radius to 2 metres
force = 500 n (halved)
.
halve the (1 m) radius to 0.5 metres
force = 2 000 n (doubled)

How can you change the density of something?
You can change the density of something by altering its mass and volume. Increasing the mass while keeping the volume constant will increase the density, while increasing the volume while keeping the mass constant will decrease the density.
What are two ways to increase the density of an object?
Density = Mass / Volume To increase density, you could increase mass or reduce volume. To increase mass, you could use a different material (metal instead of plastic) to make the object. To decrease the volume, you could change its shape (square to round) or compress it (force all the air out if there is).
Does increasing mass increase acceleration?
No, increasing mass does not increase acceleration. Acceleration is dependent on the force applied to an object and the object's mass. In the equation F = ma, where F is the force, m is the mass, and a is the acceleration, increasing mass would actually decrease acceleration if the force remains constant.
How do you change centripetal acceleration?
Centripetal acceleration can be changed by altering the speed or direction of an object in circular motion. Increasing the speed will increase the centripetal acceleration, while changing the direction of motion will also change the centripetal acceleration.
Is the entropy of the universe increasing?
Yes, the entropy of the universe is increasing over time, according to the second law of thermodynamics. This law states that in any isolated system, the total entropy, or disorder, will always increase or remain constant, but never decrease.

What factors affect the increase of the centripetal force on a particle in uniform circular motion?
Increase in radius affect the increase of the centripetal force on a particle in uniform circular motion. An increase in radius would cause a decrease in the force if velocity remains constant.

In an arithmetic sequence the constant rate of increase or decrease between successive terms is called the?
In an arithmetic sequence, the constant rate of increase or decrease between successive terms is called the common difference. This value can be positive, negative, or zero, depending on whether the sequence is increasing, decreasing, or constant. The common difference is denoted by the symbol ( d ) and is calculated by subtracting any term from the subsequent term.
What are the different curve classes and how do they differ from each other?
There are four main curve classes: linear, quadratic, cubic, and exponential. Linear curves increase or decrease at a constant rate. Quadratic curves have a single bend and increase or decrease at an increasing rate. Cubic curves have two bends and increase or decrease at a varying rate. Exponential curves increase or decrease at an accelerating rate, growing rapidly over time.
In an arithmetic sequence the constant rate of increase or decreas between successive terms is called the?
An arithmetic sequence does not have a constant rate of increase or decrease between successive terms, so it cannot be called anything!The constant increase or decrease is called the common difference.
Does increasing mass increase acceleration?

If power is constant increasing the voltage will increase or decrease current?
Decrease, because W = I (current) x V (voltage), if one increases, the other decreases in proportion to the increase of the other. Ohm's Law states current is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit.
What decreases the centripetal force?
If a body of mass m is in uniform circular motion with speed v and radius r, then the force acting on it has magnitude F = mv2 / r and is directed towards the centre of the circle. This is termed a "centripetal" (meaning "centre-seeking") force. To decrease the magnitude of the centripetal force, you must therefore either decrease the mass of the body, decrease the orbital speed, or increase the radius of the orbit.
If you increase the radius of circular motion then what is the centripetal acceleration?
That depends what you will remain constant: the angular velocity, or the speed. Here are two formulae that can help you decide: acceleration = speed squared / radius, and acceleration = angular velocity squared times radius. Angular speed should be measured in radians in this case. Angular speed is equal to 2 x pi x (revolutions per second). From the above formulae, it clearly follows that: (a) If you maintain the speed constant (and thereby reduce angular speed, a larger radius means less centripetal acceleration. (b) If you maintain the angular speed constant (and thereby increase the speed), a larger radius means more centripetal acceleration.
