Force and Motion
every force
a magnitude and direction
speed equals
distance over time
what is a balanced force
when forces are equal
What is Kinetic Energy?
Kinetic Energy is energy that is in motion.
What is Gravity?
The force that attracts a body toward the center of the earth, or toward any other physical body having mass. For most purposes Newton's laws of gravity apply, with minor modifications to take the general theory of relativity into account.
What is an example of normal force?
A still force like a table and a book sitting on a table.
They are pushing against each other
If I push you towards the wall in front of you what direction do you go
Forward
What is a unbalanced force?
A force that changes and object in motion
What is Potential Energy?
Potential Energy is energy that isn't in motion.
What would happen if we had no Gravity?
We would float
what is the definition of magnitude
how strong the push or pull is (measured in n-newtons)
what does acceleration mean
the increase in speed
If I was kicking a ball with 50n and Zion kicks the ball with 20.6n who's force is greater
My force is greater
Fill in the blank:
Energy due to motion is __________ energy.
(A) Potential (B) Kinetic
(C) Energy (D) Motion
(B)Kinetic
What has more mass, a moon or 16 Elephants?
What is Net Force?
Together gravity and the normal force combined acting upon an object
What is speed
How fast an object goes in any direction
Force that has net force of zero is what?
Balanced

True or False
A Elephant has the same mass as the Moon
True
what is force
a push or pull that can change the motion of an object
name 2 types of location
absolute and relative
Fill in the blank:
Forces can change the __________ of an object.
