## How do you find maximum speed in circular motion?

For an object near the surface of the earth F = mg and r = 6.4*106 m. The speed of the orbiting object is found from mg = mv2/r, v2 = gr = (9.8 m/s2)(6.4*106 m). We have v = 7919 m/s, or approximately 8000 m/s.

**What is the formula for circular motion?**

Equations

Equation | Symbol breakdown |
---|---|

v = r ω v = r \omega v=rω | v v v is linear speed, r is radius, ω is angular speed. |

T = 2 π ω = 1 f T = \dfrac{2\pi}{\omega} = \dfrac{1}{f} T=ω2π=f1 | T T T is period, ω is angular speed, and f is frequency |

**What is circular motion examples?**

Examples of circular motion include: an artificial satellite orbiting the Earth at a constant height, a ceiling fan’s blades rotating around a hub, a stone which is tied to a rope and is being swung in circles, a car turning through a curve in a race track, an electron moving perpendicular to a uniform magnetic field.

### What is circular motion Give 5 examples?

**What is circular motion 12th?**

Circular motion is described as a movement of an object while rotating along a circular path. Circular motion can be either uniform or non-uniform. During uniform circular motion the angular rate of rotation and speed will be constant while during non-uniform motion the rate of rotation keeps changing.

**How do you find minimum speed in circular motion?**

Explanation: The minimum or critical speed is given by vcritical=√rg . This is the point where the normal (or tension, frictional, etc.) force is 0 and the only thing keeping the object in (circular) motion is the force of gravity.

#### How do you find mass in circular motion?

This net force is often called the centripetal force. Since the acceleration of an object undergoing uniform circular motion is v2/R, the net force needed to hold a mass in a circular path is F = m (v2/R)….Force and Circular Motion.

Mass (kg) | Velocity (m/s) | Force (N) |
---|---|---|

0.035 | ± | ± |

**What is the formula for uniform circular motion?**

α = dω/dt = d 2 θ/dt 2. Circular motion can be uniform and non-uniform depending on the nature of acceleration of the particle. The motion is called uniform circular motion when the particle is moving along a circular path possessing a constant speed. During circular motion, the velocity vector changes its direction at each point on the circle.

**What are some examples of circular motion?**

Some of the most common examples of circular motion include man-made satellite that revolves around the earth, a rotating ceiling fan, a moving car’s wheel, the blades in a windmill, and gears in gas turbines. A particle is said to execute circular motion when it moves along the circumference of a circular path.

## Why is circular motion described in terms of angular variables?

An important aspect of circular motion is that the direction of motion is changing continuously unlike in the case of linear motion. Hence circular motion can also be described in terms of angular variables. It is defined as the angle turned by a rotating particle per unit time.

**When does a particle execute circular motion?**

A particle is said to execute circular motion when it moves along the circumference of a circular path. An important aspect of circular motion is that the direction of motion is changing continuously unlike in the case of linear motion. Hence circular motion can also be described in terms of angular variables.
