Force that keeps an object moving round in a circle.
Centripetal force
Centripetal acceleration moves ...
towards the center
If given revolutions per minute, how do you convert it to meters per second?
(rpm * C) / 60 = m/s [C can be written as pi*d or 2*pi*r]
A plane is circulating around a path of radius 4 km. The speed of the jet is a constant 10 km/s. What is the centripetal acceleration? (give ans in m/s^2)
25 000 m/s^2
What happens if the centripetal force is removed?
It flies of in a straight line tangent to the circle.
A 72.0 kg stunt pilot takes his plane into a steep dive. The plane follows a curved path with a radius of 360 meters while traveling at 120 m/s. What centripetal force does the pilot feel?
Fc = 2880 N
Recite all the equations we can use when dealing with Uniform Circular Motion.
T = 1/f, f = 1/T, vc = C/T = π×2r/T, ac=v²/r, Fc = mac = mv²/r
A hot wheels car moves in a circular track of 5.00 m in 10.0 seconds. What is the car's centripetal acceleration?
1.97 m/s^2
How does uniform circular motion move?
It moves in a circle, constantly changing direction while keeping a constant speed.
A wheel separated from its car is moving with a centripetal velocity of 3.98 m/s with a radius of 30.5 meters. What is the wheel's centripetal acceleration?
0.519 m/s^2
What is the difference between centripetal and centrifugal force?
Centripetal - pulls object towards the center, Centrifugal - perceived outward force experienced by the object due to inertia, pushing it away from center
