Centripetal acceleration is in the opposite direction of centripetal force. True False The normal force is always equal to the force of gravity. True False

Newton's second law for uniform circular motion

What centripetal acceleration do we undergo with respect to the sun on account of earth's orbit around the sun. Assume it's a circular orbit of radius 1.5*10^11m

Find the centripetal accelerations at each of the following points due to the rotation of Earth about its axis. (a) a point on the Equator of Earth m/s2 (b) the North Pole m/s2 (c) What two forces combine to create these centripetal accelerations?

Assuming a constant speed, identify which series best shows the relationship between the centripetal force and the radius of a circle and explain why. 20 Series 1 Series 2 Series 3 - Series 4 15 10 10

Which of these equations would you use to calculate the very least speed with which you could swing a bucket of water of mass m in a vertical circle of radius r and still keep the water in the bucket? A) v = √(rg) B) v = √(rg tan θ) C) v = √(mrg) D) v = mgh E) v = mg/r

Chapter 3 - Worksheet Material For each of the following situations involving circular motion, identify what force provides the centripetal acceleration. Draw a force diagram showing all the forces on the object. (a) The earth, rotating around the sun (b) A bicycle being ridden around a corner on a banked velodrome Move no
