SUMMARY CONCLUSION

NEWTON CAR

In this experiment, how does the 2nd law of Motion apply?

F

M A

How does the lab show/explain this relationship?

In this experiment, how does the third law apply?

Action Reaction

Canister thrown back

In this experiment, how does the third law apply?

If the force with which the canister is propelled backwards increases, what happens to the force with which the Newton Car moves forward?

F can = F car (?)

Action Reaction

Canister thrown back

Car moves forward

Newton’s third Law states that for every action there is an equal and opposite reaction.

In this experiment, how does the third law apply?

If the force with which the canister is propelled backwards increases, what happens to the force with which the Newton Car moves forward?

F can = F car (?)

Action Reaction

M A

How does the lab show/explain this relationship?

Newton’s second Law states that F=ma

What 2 ways can we increase the Force with which the canister is propelled?

NEWTON CAR LAB

1. INCREASING THE MASS of the canister: (Let’s do the Math!)

F = ma F=0.05 kg x 10 m/s/s Increase mass to = 0.5 kg-m/s/s or N 100 g or 0.1 kg

2. INCREASING THE ACCELERATION of the canister by increasing the # of rubber bands:

M = 50g (0.05kg)

A = 10 m/s/s F= ?

How does increasing the force with which the canister is propelled affect the acceleration of the Newton car?

F canister = m a car

A= f / m

Let’s do the Math!

F= 1 kg-m/s/s Increase the force: F= 2 kg-m/s/s

m= 0.1 kg

A= 1kg-m/s/s÷0.1 kg A= ?

= 10 m/s/s

Mass of the Newton car does not change?:

If the mass does not change, and we apply a greater force (more rubber bands) to propel the car forward, what happens to the car’s acceleration?

A can = f/m

force = ___ a

How does the distance the car travels relate to its acceleration?

Mass of canister is the same
