- Significant Figures- Rules for the
digit*ZERO***:** - Zeroes sandwiched between non-zero digits ARE significant. (e.g. 120.05 cm has five sig figs)
- Zeroes BEFORE the first non-zero digit ARE NOT significant. (e.g. 0.0045 cm has two sig figs)
- Zeroes AFTER the last non-zero digit ARE significant IF THE DECIMAL POINT IS THERE. (e.g. 45.200 g has five sig figs)
- Zeroes AFTER the last non-zero digit ARE NOT significant IF the DECIMAL POINT IS NOT there. (e.g. 6,500 km has two sig figs)

- Energy--
- Kinetic Energy = 1/2 m*v²
- Gravitational Energy = mgh
- Elastic Energy = 1/2 k*x²
- Dissipated Energy = Work done by friction or other forces.
- Also, Dissipated energy can be found by finding the difference between the initial and final energies.
- Hooke's Law: F=kx (k=spring constant--the slope of F vs. x graph, x=displacement of spring from rest position)

Click Here (non-YouTube version) or Here (YouTube). Free fall means an object accelerates only because of gravity. For objects near the Earth's surface, this means that acceleration = 10 m/s². When an object in free fall is thrown upward, its velocity will be zero when it reaches its highest position. When an object is thrown upward and allowed to return to its original height, its displacement will be zero. Projectile Motion--think of the amazing basketball shot. We learned that for a projectile, horizontal velocity is CONSTANT, while vertically the object accelerates because of gravity (10 m/s^2 on earth). To solve projectile motion problems, first split the problem into HORIZONTAL and VERTICAL parts, fill in what you know, use one part of the problem to solve for TIME, and use that time with the other part to solve for what you're looking for.See a video tutorial of how to solve a Projectile Motion Problem Involving Angles.

Online Help: Extra help of Unit 6: The Physics Classroom: Free Fall Unit 5 Notes: (Unbalanced Forces, F=ma)Notes from class: Newton's 2nd Law: Net Force = Mass x Acceleration. The Net Force can be found by taking R - L, or L - R, or U - D, or D - U. How do you know which one? Take the direction it accelerates to be positive, then subtract forces in the opposite direction. So if something accelerates to the Right, it will be Right minus Left. Friction: We learned a formula for determining the amount of friction acting on an object: Ff=(mu)*FN. We have learned about Acceleration before--Kinematics. We can use kinematics equations to find acceleration, and then plug that into F=ma I created an EPUB version of the notes for this unit.
