Newton's First Law
A property of matter that describes the tendency of an object to resist changes in its state of motion.
What is inertia?
The formula for Newton's Second Law is this.
What is force = mass x acceleration?
Force is measured in these.
What are Netwons?
If the same amount of force is applied equally to two objects with different masses, what statement can be said about the acceleration rate?
What is the object with less mass would move faster.
A force that opposes motion.
What is friction?
According to Newton's first law, a ball rolled on the floor should roll like this.
What is a straight line forever?
This is a change of an object's speed or motion over time.
What is acceleration?
Unbalanced forces results in net forces that are not what?
What is zero?
This will stop and object.
What is a push or a pull?
A push or pull.
What is force?
This unbalanced force would eventually stop an object from rolling.
What is friction?
If the sum of the forces on an object are nonzero (unbalanced) then the object will accelerate this way.
A force has opposite directions but equal magnitudes. The force pulling to the left is -20 N and the force pulling to the right is 40 N. What is the net force?
What is 20 N
Gravity pulls objects where
What is towards the Earth's center?
The force of attraction that exists between any two objects that have mass.
What is gravity?
The more massive an object is, it requires this.
What is more inertia?
Is the mass of an object was tripled, this amount of force would need to be applied to the object.
What is tripled?
A net force has these two components.
What is a magnitude and direction?
If you are sitting on a train your frame of reference would be what?
What is the train?
A force that has unequal magnitudes and/or directions.
What is an unbalanced force?
If an object is at rest and then suddenly moves, the change was caused by this.
What is an unbalanced force?
An increase in acceleration on a graph would result in it being graphed in this manner.
What is a straight line?
If the net force is not zero, it could cause an object to do which three things?
The reason an object wouldn't fall off of a table is due to gravity is this.
A equal force is pushing up on the object.
What is a frame of reference?
