Discussion: A __________is any push or pull on an object and is measured in Newtons.
______________ forces are forces that are equal and opposite. ________________forces can
cause a change in motion. According to Newton’s 2nd Law of Motion, if a net force is applied to
an object, the object will __________ in the direction of the force. ________is the amount of
matter in an object and it is measured in kilograms. ____________________________is the rate
of change in velocity that can be caused by speeding up, slowing down, or changing the direction
of the motion and it is measured in m/s/s. All objects on Earth fall at an acceleration rate of
_______m/s/s in the absence of friction or air resistance.
Procedure
1. Choose a planet under Location 1 and a different location under Location 2 then choose an
object that is the same for both locations. Record your locations and your object in the data table.
2. Record the rate of acceleration for each location and the object’s mass in the data table.
3. Click the drop
button & observe the object’s fall. The green lines indicate the object’s
position at each second.
4. Calculate the force of the objects (weight) using Force = Mass x Acceleration. Record in your
data table.
5. Repeat steps 1 – 4 for another object in the same locations.
6. Repeat steps 1 – 4 for the object in step 5 but with two different locations.

Conclusion
1. How
is
Newton’s
Second
Law
related
to
gravity?
2. How
does
the
force
of
gravity
affect
the
rate
of
acceleration?
3. Describe
how motion is affected when the same object is dropped on different planets.
4. Describe
how motion is affected if two objects of different masses are dropped on the same
planet.
5. According to your data, what is the relationship between mass and weight?
