VelocityVelocity the the rate change of an object. With respect to frame reference velocity is equal to the specification of the objects speed and motion or direction.
ForceForce is an opposite interaction of an objects motion. Force affects an objects velocity with mass. Any push or pull may be described as force.
Potential EnergyPotential energy is energy held by an object, this is built up energy that can be elastic or non elastic. This energy may also be gravitational or potential.
Mechanical AdvantageMechanical advantage is force measured by amplification. Due to amplification movement is attained and it's outlet would be force. This force is very useful due to the force that is being applied.

AccelerationAcceleration is the velocities rate of change, repect to time acceleration is vector quantities made of or magnitude direction.
WorkWork is an energy transfer when an object is forced with displacement. Work may have a positive force (when applied) or a negative force (when applied)
Kinetic EnergyKinetic Energy is motion released energy, Unless there is a difference in speed during the process of motion, it will remain the same until the object decelerates.

Here is how you find the velocity of an object:
(V=△ d /△ t) This may look a little tricky at first once you break it down it is very simple.
|
Here is how you find the acceleration of an object:
(a=△ v / △ t) This may look a little tricky at first once you break it down it is very simple.
All you need to do is divide the Velocity by the time to get the acceleration! |
Here is how you find the force of an object:
(f = m * a) This may look a little tricky at first once you break it down it is very simple.
All you need to do is multiply the mass by the acceleration to get the force! |
Here is how you find the work of an object:
(w = f * d) This may look a little tricky at first once you break it down it is very simple.
All you need to do is multiply the force by the distance to get the work ! |
Here is how you find the Potential Energy of an object:
(PE = M*G*H) This may look a little tricky at first once you break it down it is very simple.
All you need to do is multiply the mass by the acceleration and the height to get the Potential Energy! |
Here is how you find the Kinetic energy of an object:
(KE = mv) This may look a little tricky at first once you break it down it is very simple.
All you need to do is multiply the distance by the time to get the Kinetic Energy! |
Here is how you find the Mechanical of an object:
(MA = d/ h) ) This may look a little tricky at first once you break it down it is very simple.
All you need to do is divide the distance by the height to get the Mechanical Advantage! |

Strengths I would feel confident saying our teams biggest strength was communication and cooperation. Any time we had any confusion we would e-mail or message each other right away without hesitation.
|
Challenges A challenge for our group was speeding up our process, and stay on track. We did take time off to work on our machine which bumped us back just by a little but we got back to it.
