The same amount of force is applied to two bowling balls. One of the balls weighs 8 pounds and the other weighs 13 pounds. Which ball will have greater acceleration"

The potential energy of an object is equal to the work required to lift it into position. True or False?

To get better acceleration, you want to reduce the inertia of your bicycle. You have your choice of spending $45 on only one of three light-alloy items, each reducing the inertia of your bicycle by the same amount: A. a new seat post, B.
