1 Newton’s Second Law Force equals mass times acceleration. F = ma

2 Newton’s Second Law The greater the mass of an object, the more force it will take to accelerate the object.  Force = Mass x Acceleration Force is measured in Newtons On Earth, weight is a measurement of the force of gravity.

3 Newton’s Second Law One rock weighs 5 Newtons.
The other rock weighs 0.5 Newtons. How much more force will be required to accelerate the first rock at the same rate as the second rock? Ten times as much

4 Remember

5 Circular Motion Centripetal Force: Any force that keeps an object moving in a circle Without the force, the object would go flying off in a straight line Video Video 2
