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?

One way to increase the density of an object is by increasing its mass while keeping its volume constant. This can be achieved by adding more material to the object. Another way is to decrease the volume of the object while keeping its mass constant, which effectively increases the mass per unit volume, thus increasing its density.


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.

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.

What is the opposite of increased?

The opposite of increase is decrease or reduce.

What is the result of increasing the temperatue of a gas?

At constant volume the pressure increase.


What will always increase voltage?

increasing resistance and keeping current constant


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.
