What is a Force?3Category 1 - 10State Newtons 2nd Law of Motion.What is Kinetic Energy?

A Force is a push or pull on an object.Back to MenuWhat does this diagram represent?

Balanced: equal but opposite forces create a net force of 0; there is no movement.

Unbalanced: unequal forces create a net force; object movesBack to MenuA 46kg cannonball is shot out of a cannon. If it is accelerating at 5m/s2, what is the Force acting on it?

An object at rest will remain at rest, and an object will remain in motion unless acted upon by an unbalanced force.

Also known as the law of Inertia.Back to MenuEnergy comes in 6 different forms. Name 3 of them.DAILY DOUBLE!

The wagon of girl scout cookies you need to move has just too much inertia. Using Newtons 2nd Law, how can you move the wagon?

5 Point Bonus: What is a second way?

State Newtons 1st Law of Motion. What is it also known as?7How can Newtons 2nd Law be rewritten to solve for Acceleration? For Mass?What are 2 ways that you can increase an objects Potential Energy?What is Nuclear Energy, and how can it be released?

Explain where the Kinetic energy and potential energy are both at their highest and lowest in the diagram.

F = m x a

a = F m

m = FaBack to Menu

You are doing your part to keep the science room clean by flipping your lab stool onto the table. The stool has a mass of 4kg. When flip the stool up, it accelerates at 2m/s2. How much force do you generate by flipping the stool? Unfortunately, NO ONE else is helping. So you stoically flip your stool and 33 others. Force?Which has more Momentum?A 6kg sledgehammer swung at 1.5m/s.A 2.5kg hammer swung at 4m/s.

What is Thermal, Chemical and Electrical Energy? Give an example of each or how you would measure them.While you were floating in space taking pictures with your camera, a small asteroid hit your ship and pushed it away from you. How can you use Newtons 3rd Law to get back to your ship?

_______ is famous for discovering __________ . His observations on objects in __________ revealed that acceleration due to gravity is _____ . His laws of ________ help us understand the behavior of objects. These rules, in order, are ________ , F = m x a, and __________ . It took until the 1900s before these laws were improved by _________.603010motionfree fallconservation9.8m/s2 gravityEinsteinMomentumNewton inertia4.9m/s

Back to MenuNewtons 3rd states that for every action, there is an equal and opposite reaction.

By increasing the height of the object OR by stretching it.Back to Menu

Which has more Momentum?Momentum= 6kg x 1.5m/sMomentum = 9kg.m/sMomentum= 4kg x 2.5m/sMomentum = 10kg.m/sBack to MenuFinal JeopardyEnergy is the ability to do Work, measured in Joules.

Nuclear Energy is the energy stored in the nucleus of an atom, released during fusion (combining) or fission (splitting) of atoms.Back to Menu

Thermal: energy of particles in an object; measure with thermometer IceChemical: energy stored in chemical bonds; FireElectrical: energy of moving electric charges; Lightning

The diagram represents an unbalanced force with the net force in the downward directionBack to Menu

You can decrease the wagons mass by removing some cookies.

Or you could reduce the friction on the wheels with ice or oil.

Back to MenuKinetic energy is highest at point 3 and lowest at 1 and 5. Potential energy is highest at points 1 and 5 and lowest .

By throwing your camera!Newtons 3rd Law:

Action Reaction is = and opposite

The force you exert throwing your camera is equal to the force the camera exerts on you, moving you back towards your ship.

Final JeopardyBack to MenuSTOPNewton is famous for discovering gravity. His observations on objects in free fall revealed that acceleration due to gravity is 9.8m/s2. His laws of motion help us understand the behavior of objects. These rules, in order, are inertia, F = m x a, and momentum. It took until the 1900s before these laws were improved by Einstein.Back to Menu
