Period 7 Semester Exam Review by Thomas E Clark https://padlet.com/tec430/gc3yh2wt27ii We have covered concepts related to Motion (both one and two dimensional, linear and circular), Forces, Energy, and Momentum (angular and linear). The main question is ,"How are all these concepts connected"? Why is this important? Because through consolidation it makes it easier to manage, understand and thus retain (remember) the information that you learned. Instructions: Each group (table) will be given one of the following: (1) A Topic to list every concept covered under that topic or (2) The task to list how concepts under two assigned topics are related. The exercise is class lecture where you generate the content and I lead the discussion. en-us 2016-12-05 22:55:07 UTC 2025-05-17 16:39:07 UTC hello@padlet.com Motion: Force (Tamera & Bonny) https://padlet.com/tec430/gc3yh2wt27ii/wish/141902544 You need acceleration to have force because Force(N)= Mass(kg) x Acceleration (m/s^2).
A turn results in acceleration, so even if there's no change in velocity, there is still force.
Newton's First Law states that an object at rest or in motion will remain that way unless some type of force is applied. ]]> 2016-12-05 23:03:24 UTC https://padlet.com/tec430/gc3yh2wt27ii/wish/141902544 E https://padlet.com/tec430/gc3yh2wt27ii/wish/141902731 2016-12-05 23:05:38 UTC https://padlet.com/tec430/gc3yh2wt27ii/wish/141902731 Force (Chisondi and Rachel https://padlet.com/tec430/gc3yh2wt27ii/wish/141902781 Force= Mass * Acceleration
(Newton's Second Law)
Tension Force is transmitted through a string, rope, cable or wire when it is pulled tight by forces acting from opposite ends
When going around a curve, an object follows Newton's second law because there is acceleration since a change in velocity occurs.
Force can be caused by magnetism, gravity (anything causing mass to accelerate).
Has magnitude and direction
Measured in Newtons
Related to thrust, drag, and torque

2 Types
Kinetic energy: KE=1/2 MxV^2
Kinetic is the energy is associated with motion energy.
Types of kinetic energy are Mechanical energy, thermal energy, and electrical energy. When the temperature increases the movement of molecules increases
Potential energy: PE=MxGxH
Potential energy is not stored energy. The higher the temperature the more the potential energy. Types of potential energy are gravitational energy like roller coasters, electromagnetic energy such as magnetic and electric potential energy, and weak nuclear potential energy such as radioactive decay. Displacement of PE is the height. M time G is also connected to newtons second law Which is F=MxA]]> 2016-12-05 23:06:51 UTC https://padlet.com/tec430/gc3yh2wt27ii/wish/141902839 Motion:Energy(Diana R., Catlan, Sakshi) https://padlet.com/tec430/gc3yh2wt27ii/wish/141903002 Stored energy does not create motion whereas the energy of motion is kinetic energy.
KE=.5mv^2
Energy is a property of matter that results by interacting with forces, and since exerting force changes motion (acceleration), the energy of the force determines the motion of an object, which is Newton's First Law. 
Potential energy has no motion while kinetic energy has lots of motion. 
Thermal energy is the result of particles moving in fast motion. Work is defined as the the force that acts upon an object to cause a displacement of the object. The equation for work is W=F*d*costheta. The unit of work is Joule and 1J=1N*m. 
Temperature is the measure of the average kinetic energy of the molecules in a material. 
The conservation of energy is shown through the shift of kinetic energy to potential energy and vice versa. ]]> 2016-12-05 23:09:03 UTC https://padlet.com/tec430/gc3yh2wt27ii/wish/141903002 Energy: Momentum (SITARA AND JORDAN) https://padlet.com/tec430/gc3yh2wt27ii/wish/141903137 -Momentum (p) = Mass (m)  x Velocity (v)
-Units of momentum are kilograms x meters/second
-When objects interact/collide they impart a force to the other object.
-Impulse and momentum are different but they are equivalent
-An impulse of 20 N imparts 20 kgm/s of momentum
MOMENTUM AND COLLISIONS
-Two kinds of collisions: elastic and inelastic
- Elastic collision: objects rebound from each other completely without any energy lost
Example: cue ball hitting another ball
-Inelastic collision: objects stick together or become deformed
Example: a car hitting a wall. Wall becomes deformed and car becomes deformed
ENERGY
-Kinetic and potential energy 
-Law of Conservation of Energy: energy can neither be created nor destroyed only transformed and transferred
-Examples: In elastic collisions, energy is not lost, only transferred from one object to another. 
Examples: In inelastic collisions, energy is lost in the form of heat when the two objects collide because it is not transferred from one object to another.

Newtons 2nd Law tells us that the F =ma 
F= m(velocity/time) = (mass x  velocity)/ time = momentum = time 
force x time= momentum 
Related by having the force be the rate at which momentum changes with respect to time 
F= (dp/dt)
Newton's 3rd Law gives the conservation momentum

Newton's Third Law states that for every action there is an equal and opposite reaction.
