Newtons First Law
What is a balanced force?
Define: Relationship
Ex. Describe the relationship between blah blah blah
The correspondence between two variables
What is the equation of Newtons Second Law?
Force= Mass x Acceleration
What is Kinetic Energy?
Energy that an object possesses due to its motion
What is Newton's Third Law?
For every action there is an equal and opposite reaction
What is an unbalanced force?
A force that changes the motion or speed of an object
Define: Force
an influence that can change the motion of an object
push or pull
What is Newtons Second Law?
The acceleration and net force are directly proportional and there is an inversely proportional relationship between acceleration and mass.
F= ma
Describe the relationship between Kinetic Energy and Mass
The combustion force pushes toward the ground which pushed the rocket upward
What is Newtons First Law?
Related so that as one increases, so does the other or when one decreases, so does the other
How are force and mass related in Newtons Second Law?
Force and Mass are directly proportional to one another
Describe the relationship between Kinetic energy and Speed
Kinetic Energy depends on the speed squared
How does Newtons Third Law explain how we walk?
When we step our foot exerts a backward force on the ground and the ground exerts a forward force on our feet which pushes us forward.
Use Newtons First Law to explain what would happen if an astronaut pushed off a space station.
If an astronaut pushed off the space station they would remain in motion forever unless acted upon by another force.
What is a line graph and why is it used?
A line graph shows the relationship between two variables like KE and Mass. It is data points connected to show the relationship.
How are acceleration and mass related to one another in Newtons Second Law?
They are inversely proportional
What is potential energy?
While driving down the road, a firefly strikes the windshield of a bus and makes a big mess right in front of the driver! The firefly hit the bus and the bus hit the firefly. Which of the two forces are greater: the force on the firefly or the force on the bus?
Neither! The forces are equal and opposite!
Describe an experiment you could do to prove Newtons First Law. Make sure you use the law to explain and provide evidence.
Miss Lloyd's choice :)
Define: Inversely Proportional
Related so that when one increases, the other decreases.
If Billy has two boxes of the same size, one full of bricks and the other full of feathers, they have to be pushed 20 feet. How can you use Newtons Second Law to describe what Billy needs to do with the boxes?
Billy will need to apply more force to push the box of bricks than the box of feathers.
