Physics Formula Sheet For Circular Motion

The distance an object moves in a circular motion is the circumference of the circular motion which is equal to 2 pi r. Linear speed and tangential speed gives the same meaning for circular motion.

Iii ω ω 0 2αθ.

Physics formula sheet for circular motion. The formula for uniform circular motion. Subsequently if the speed of the object is doubled the net force required for that object s circular motion is quadrupled. If the radius of the circular path is r and the magnitude of the velocity of the object is v.

I ω ω 0 αt. S frequency f number of revolutions per second units. The factor by which the net force is altered is the square of the factor by which the speed is altered.

For a constant mass and radius the fnet is proportional to the speed2. Relations between different variables for an object executing circular motion are called kinematic equations in circular motion. Then the radial acceleration of the object will be.

The formulas that correspond to this type of motion. The relationship between linear quantities and angular quantities. S 1 or hz 4.

Ii θ ω 0 t frac 1 2 αt. Rotational motion cheat sheet tangential speed linear speed. Using the definition of circumference c π 2 r and the definition of velocity v d t we can derive this formula.

Its si unit is m 2s 2. 2πr which is the circumference of the circle object. In this section we are going to study.

Iv θ t ω 0 frac 1 2 α 2t 1 v θ left frac omega omega 0 2 right t. A body performs an uniform circular motion u c m when its trajectory is a circumference and its angular velocity is constant. A rad frac v 2 r again this radial acceleration will always be perpendicular to the direction of the velocity.

In linear motion at constant acceleration we have three motion equation v u at v u 2as s ut 1 2at similarly in circular motion we have equation f i t f i 2. Tangential velocity if motion is uniform and object takes time t to execute motion then it has tangential velocity of magnitude v given by v s t f 1 t period of motion t time to complete one revolution units. It can be defined as distance taken in a given time.

If the object has one complete revolution then distance traveled becomes. T 1 2 t you can use this formula to solve the numerical problem for circular motion questions we will continue in next post i hope you have enjoyed learning physics circular motion equations thanks for reading. Draw the circular motion two radii and two velocity vectors.
