Centripetal Force
... How can the second law help find net force? • If you know an object’s mass & acceleration, you can use Newton’s second law to find the force by using the equation F=ma. • Suppose a tennis ball leaves a racket with a speed of 100 km/h with an acceleration of 5,000 m/s2. The ball’s mass is 0.06 kg. F ...

Newton`s First Law - Swift
... Your students will be dropping various objects to the floor to see if they fall at different rates. Go over the background material to the level you think is appropriate for your class, but do not go over the concept that acceleration is independent of the mass of the falling object! They will find ...

The pulling force of the string on the ball acts as centripetal force and causes the ball to change direction continuously, or accelerate into a circular path. Without the unbalanced force acting on it, the ball would continue in a stra ...
