A ferris wheel
Circular/Round & Round Motion
This force causes a change in an object's motion
unbalanced
The way an object's motion is described relative, or compared, to the motion of an object in the background
What is relative motion
Balanced forces cause a change in an object's motion
What is false
Is an object's weight or mass affected by gravity?
weight
A child on a swing
back and forth motion
When an object is in a state of equilibrium
What is balanced
What is an object's motion compared to a frame of reference
What is relative
Motion is caused by a force pushing or pulling on an object
True
The point where and object's weight is even on all sides
center of gravity
a child jumping on a trampoline
up and down motion
What is balanced
When two objects move at the same speed, what kind of motion do they have
No motion
Two objects moving at the same speed have zero relative motion
true
an object is more stable if it has a low or high center of gravity?
low
a gymnast walking on a balance beam
straight line motion
Forces that are either unequal in size, not opposite in direction or both
unbalanced
This is a background object to which an object's motion is compared too
What is frame of reference
Energy gives force to an object
false
This is the force that attracts objects that have mass
what is gravity
neutron radiation
These forces are unequal in size, not opposite in direction or both
what is unbalanced
When an airplane takes off, what is your frame of reference
What is the ground
Far objects have the strongest gravity between them
False
this is an object's mass times its acceleration
weight
