Fill in the blanks:
_____10____________ is a push or pull on an object.
__________11__________________ is the difference between two opposing
forces. Newton’s 2nd Law of Motion states that if a net force acts on an object, the
object will ________12____________ in the direction of the force. Acceleration is
a change in ____13_________. It can either be ________14___________ or
_______15_____________. Mass is the amount of matter contained in an object.
Mass does not change with changes in _____________16____________. The
1

acceleration of any object falling to the surface of the Earth is
__________17________________. This means that at the first second, the object
will be falling with a speed of 9.8. m/s2. At 2 seconds, the object will be falling at
the rate of __________18___________________; at 3 seconds, it will be falling at
the rate of _________19__________________, and so on.
Procedure for Simulation
A. Copy down the Data Table below.
B. Click the arrow under Location 1 & select any planet. Click the arrow under
Object 1 selection the Pumpkin. Record the rate of acceleration for this
location and the object’s mass in the data table. Select another planet & the
Pumpkin under Location 2 & Object 2. Record the information.
C. Click the Drop button and observe the object’s fall. The green lines indicate the
object’s position at each second.
D. Calculate the force of the objects (weight) using Force = Mass x Acceleration.
Record.
E. Tests 3 & 4: Repeat steps 1-3 for the Car.
F. Tests 5 & 6: Repeat steps 1-3, but select the planet Venus for both locations
and choose any object.
G. Tests 7 & 8: Repeat steps 1-3, selecting Jupiter for both locations and choose
any object.
H. Tests 9 & 10: Repeat steps 1-3, selecting any planet and any object.

23. Describe what happens when different objects are dropped under the same
gravitational conditions.
24. Based on your data, how does mass affect weight?
25. What is the weight of a 24.52 kg Television dropped on Pluto
(acceleration of 0.59 m/s2)?
26. What is the weight of a 45.40 kg Barbell dropped on Earth?
27. A hammer is dropped on Planet X. If the hammer has a mass of 3kg and a
weight of 9N, what is the gravitational acceleration of Planet X and is it more or
less than that of Earth?
