https://padlet.com/tec430/bx4jgfx4v42x 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 2016-12-02 19:58:31 UTC 2023-05-18 13:13:57 UTC hello@padlet.com https://padlet.com/tec430/bx4jgfx4v42x/wish/141800516 PE = m*g*h
- PE= potential energy
- m = mass (kg)
- g = gravity (m/(s^2))
- h = height (m)
Define: Stored energy of an object.

KE = 1/2 (m)(v)^2
- KE = Kinetic Energy
- m = mass (kg)
- v = velocity (m/s)
Define: Energy of an object in motion.

Determine on a graph the highest and lowest PE and KE.

Ffrict=(mu) (Fnorm)

Elastic Collison- no loss of KE

Inelastic Collisions- KE is converted to another energy

Straight line:
p = mV
   = F*deltaT
   = ∫ m*a(dt)
F*delta T=Pf-Pi
Angular Impulse
L = I*W (W = angular velocity, I = resistance to motion)
Momentum is conserved in collisions. This can be expressed as P1i+P2i=P1f+P2f
Collisions can be characterized as elastic or inelastic, depending on if the objects separate.
For elastic collisions M1V1i +M2V2i = M1V1f + M2V2f
For inelastic collisions M1V1i +M2V2 =  (M1+M2)*Vf

Newton's Second Law states that force is related to acceleration, as reflected in the equation F=m*a. This means that the more force applied to an object, the more it accelerates. This it true in multiple circumstances, including circular motion. In circular motion, an object constantly changes the direction of velocity, causing acceleration, and therefore, a force on the object in motion. This force is called centripetal force, which pulls the object towards the center. In addition to this, the net force in circular motion is equal to the centripetal force. Also, both forces and motion can be expressed in vectors. Both have direction and magnitude. Net force is equal to zero when an object is at rest or at constant velocity, meaning that all the forces have an equal force opposing it, cancelling each other out.

Applied Force- is force applied by a human or another object to an object.
Gravitational Force-gravity is defined as the weight of an object.
Fgrav= m * g g=9.8 N/kg and mass is in kg.
Normal Force- force exerted upon an object that is in contact with another stable object.
Frictional Force-force exerted by a surface as an object moves across it or makes an effort to move across it
Force has both has magnitude and direction.
Magnitude=((x^2)+(y^2))^(1/2)
Direction= tan^-1(x/y)]]> 2016-12-05 16:45:05 UTC https://padlet.com/tec430/bx4jgfx4v42x/wish/141801148 https://padlet.com/tec430/bx4jgfx4v42x/wish/141801279 Newton's first law states that an object in motion stays in motion, therefore the object in motion has kinetic energy.In addition, the law of inertia states that an object at rest stay in rest, meaning it possess potential energy.

Energy can be transferred by forceful contact between two bodies - collisions. There is a range of 'elasticity' to describe these collisions. Inelastic (a system loses momentum - though it is conserved in unobserved objects) and Elastic (a system does not lose momentum - the momentum is fully transferred from one object to another, or is shared equally between the objects involved in the collision)

Potential energy is the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.

Kinetic energy is energy possessed by a body by virtue of being in motion.

*force x time = momentum
-difference between force and momentum is time.
 F[1->2] = -F[2->1]
(Newton's Third law says that for a force exerted by object 1 on object 2, object 2 exerts a force on object 1 that is equal in magnitude and opposite in direction to the force object 1 exerts).
