Newton's 1st law of motion
Sitting still and stationary.
Which one of Newton's laws of motion is this an example of?
Ex. A car accelerates faster than a truck.
Newton's 2nd law of motion.
Example: Gravity is pulling you _____ in your seat, but your seat is pushing up against you with _____________. This is why you are not moving. There is a ________________ acting on you.
Down, equal force, and balanced force.
The force of an object comes from its ____ and its _______.
Mass and acceleration.
Force is directly proportional to _____ and ___________.
Mass and acceleration.
An object will " _________________ ______________" unless acted on by an __________ _______.
Keep doing what it was doing and unbalanced force.
Force _____ mass times acceleration (F=ma)
Equals.
For every _____, there is an equal __________.
Action and reaction.
It takes an _______ ________ to change the motion of the object.
Unbalanced force.
A measurement of how quickly an object is changing speed, direction or both.
Acceleration.
Things don't keep moving forever because there's almost always an unbalanced for acting upon it. Two common forces that prevent things from moving forever are ________ and ________.
Friction and gravity.
The Second Law of Motion says that when a force _______ or _____ on an object, the object will move in the same direction as the force.
Pushes and pulls
Which one of Newton's laws is this an example of?
Ex. The floor pushes up as a person's foot pushes down.
Newtons 3rd law of motion.
A force is a ____ or a _____.
Push or Pull.
If you double the mass, you double the ____. If you double the acceleration, you double the ____.
Force.
It takes an unbalanced force to _____________ ________.
Change the motion of an object.
What law is this?
larger net force acting on an object causes a larger acceleration, and objects with larger mass require more force to accelerate.
What law of motion is this?
If object A acts a force upon object B, then object B will exert an opposite yet equal force upon object A.
Newton's 3rd law of motion.
Force is _________ ____________ to mass and acceleration.
Directly proportional.
The force of an object comes from its mass and its ___________.
Acceleration.
The more ____ an object has, the more _____ (harder to change its motion).
Mass and inertia.
If you ______ the mass you _______ the force. If you _______ the acceleration, you _______ the force.
Double.
For every force acting on an object, there is an ______ force acting in the ________ direction.
Equal and opposite.
The rate at which ________________________.
An objects position changes.
A force can make something speed up, or ___________.
Accelerate.
