How is centripetal force affected by mass?
Centripetal force = mv2/r, where m is mass, v is the velocity, and r is the radius
How do you find tangential velocity?
Tangential velocity is equal to (mass x velocity^2)/radial distance
Quantity that remains constant during uniform circular motion?
-- tangential speed -- angular velocity -- kinetic energy -- magnitude of momentum -- radius of the circle -- centripetal acceleration
What is tangential velocity and tangential acceleration?
Vt=w*r where; * is multiply Vt is tangential velocity w is omega(angular mometum) r is radius
What is the tangential velocity of the puck rotating on top of the table?
The tension in the rope must generate the centripetal acceleration holding the hockey puck on its circular track T = m vt 2/ R vt= [T R / m] = [(9.81 N) × (1 m) / 0.25 kg] = 6.25 m/s
What is the tangential velocity and centripetal acceleration of the earth moving around the sun?
Tangential velocity squared is GMs/r and velocity v =29814m/s and the centripetal acceleration is v2/r= 5.928 E-3 m/s2
Is the tangential velocity of a rotating object greater when it is close to the center of rotation or when it is far from the center of rotation?
The tangential velocity is greater as the radius of the point on the rotating object increases. For a rotating object v = rw Where v is the tangential velocity r is the radius of the point And "w" is omega or angular velocity (in radians per second)
How do you increase the angular velocity of a rotating object?
Angular velocity just means how fast it's rotating. If youaa want more angular velocity, just rotate it faster or decrease the radius (move it closer to the center of rotation). Just like force = rate of change of momentum, you have torque= rate of change of angular moment Or We can increase the angular velocity of a rotating particle by applying a tangential force(i.e. accelaration) on the particle. Since the velocity of the particle is tangential with the circle along which it is moving, the tangential accelaration will not change the diriction of the velocity(as angle is 0),but will cause a change in magnitude. Thus angular velocity will increase.
Can a car move around a circular racetrack so that the car has a tangential acceleration but no centripetal acceleration?
No, If a car moves around a circular race track with any constant speed, the acceleration is directed towards the centre. So it has a centripetal acceleration. The tangential acceleration would be irrelevant unless the car has an instantaneous tangential velocity of zero. Then the centripetal acceleration is zero. However, this would only exist for that small instant in time.
How is centripetal force affected by mass?
Centripetal force = mv2/r, where m is mass, v is the velocity, and r is the radius
How do you draw velocity and acceleration diagrams?
Velocity diagrams are drawn perpendicular to the link ....whereas acceleration diagrams are drawn by knowing the values 2 components radial or centripetal component and tangential component.......the radial component moves parallel to the link and perpendicular to the velocity diagram.....but the tangential component moves perpendicular to the link and parallel to the velocity diagram .
How do you find tangential velocity?
Tangential velocity is equal to (mass x velocity^2)/radial distance
Describe the motion of a satellite relative to the direction of gravity at any moment in time?
Derive acceleration relative to time and plot the resultant velocity (centripetal and tangential) as a vector.
Quantity that remains constant during uniform circular motion?
-- tangential speed -- angular velocity -- kinetic energy -- magnitude of momentum -- radius of the circle -- centripetal acceleration
Will magnitude of accleration be constant if oject travels in constant speed in circular path?
Short answer: yes.The force required to maintain constant-velocity circular motion is called centripetal force, and it acts toward the center of the circle (perpendicular to the object's tangential velocity). Centripetal force is given byf_c = mv^2 / rwhere m is the mass of the orbiting object, v is its tangential velocity and r is its (presumably constant) distance from the center of rotation. Centripetal acceleration is given by dividing both sides of this equation by m (as governed by Newton's second law).
What kind of velocity is provided by the news channel in reference to a tornado Is it tangential velocity or angular velocity?
In terms of wind velocity, it would be tangential velocity, as that is what tells the speed at which the wind is actually moving. Though in truth it is somewhat more complicated than this, as a tornado does not behave as a simple rotating object. In terms of a tornado's traveling velocity, it is linear velocity, as a tornado will generally move along a mostly straight path.
