Extra credit-read all about it! Review a science times article for 2 pts. extra credit.
A projectile fired from the equator, straight north, is also moving east at 1000 mi/hr. Because the target is moving east slower, the projectile will land to the right of the target.
Coriolis effect 800 mi/hr east 1000 mi/hr east If it takes the projectile 1 hr to reach its target, it will be 200 miles east of the target.
Coriolis effect 800 mi/hr east 1000 mi/hr east A projectile crossing lines of latitude in the northern hemisphere, will land right of its target.
Angular velocity is the rate at which an object rotates is the symbol used for angular velocity
Coriolis effect 1000 mi/hr east 800 mi/hr east A projectile crossing lines of latitude in the southern hemisphere will curve to its left.
2 pts. Extra credit Fill the bath tube and let the water sit for 15 minutes. Put a floating object in the water and pull the plug.
Will the projectile hit its target? X 800 mi/hr 800 mi/hr Yes, if we have a flat earth. Which way does the water rotate?
A little vector addition Resultant path 200 mi/hr east Projectile fired north Actual path is to the right of the target.
Centripetal force The door pushes the passenger toward the center. V V Fc The door pushes the passenger toward the center.
Centripetal acceleration V ac R ac ac Acceleration toward the center of the circle. What two things effect the centripetal acceleration?
Centripetal force V Fc R Force toward the center of the circle.
Why did Batman shoot the cable at the light post?
Centripetal force Force toward the center of the circle. V Fc Batmobile R Force toward the center of the circle.
Torque-the turning effect of a force d pivot Torque is the product of the perpendicular component of the force and the distance to the pivot.
Torque and force are not the same thing. Say it with me!
Moment of inertia d1 d2 M1 M2 Center of rotation
Moment of inertia is an object’s resistance to a change in its angular velocity Angular velocity is the rate at which an object is rotating.
