Newtons 2nd Law - F=ma - Does Mass Matter Lab

You use this machine to measure...

• Force in Newtons

• Mass in grams

• Acceleration in m/s2

• all of the above

The mass of your tumble buggy alone in kg was approximately...

• .1 kg

• 100kg

• .38kg

• 120 N

What number represents 1000ths (the number we used to represent the force in this lab).

• .01

• 1

• .009

One newton can best be described as ... how much force it takes to move an object with...

• 1kg of mass, 1 meter per second

• 100 kg of mass 1 mile per hour

• 5 lbs of mass, a kilometer

• move a childs scooter around the neighborhood

What symbols do we use to represent acceleration? (or meters per second every second)

• mph

• m/s

• kg

• m/s2

Which math formula did you use to calculate the force that the tumble buggy exerted on the wall (unmoving object)?

• s/t=d

• mxa=f

• d/t=s

• none of the above

In the end you were able to clearly show in your data that...(look at your graph silly)

• More mass on car. the more force exerted on the wall

• Less mass on car. more force exerted on the wall

• There was no correlation between the mass on the car and the force on the wall.

• Halloween is my favorite holiday of the year.
