very useful formula for solving problems. and can be derived directly from the definition of acceleration using Calculus. This derivation is usually reserved for students in either Engineering Principles I (Dynamics) or the Junior Level Mechanics class for Physics and Engineering Physics Majors. You will probably prefer . just to memorize the ...

The key is that, when solving problems, we can choose any CS we wish without changing the physics. If we have a vector in an orthogonal CS like the left hand side of figure 6, we can rotate the CS such that the vector is aligned along the x-axis of the new CS. Then we can express the vector simply as .

When solving projectile problems, motion in the horizontal is analyzed independently of motion in the vertical (vector analysis). Since air resistance is ignored, there is . no acceleration in the horizontal direction so the x-component of velocity remains constant for the entire time of flight.

Other things are from worksheets. Be sure to do the Problems, not the Questions. (If you are IB, you should try to answer the questions as practice) Solutions for many of the problems are on my website if you get stuck – answers to odd problems are in the back of the book and you need to check them yourself.

The key to solving projectile problems is to resolve the initial velocity into components perpendicular and parallel to the direction of the force of gravity. The motion perpendicular will keep its initial velocity component and continue to move at this constant velocity.

Part 1: Working out the component of a vector in a particular direction. Part 2: Solving problems using components. There are questions for you to try at the end of each part. Part 1: Working out the component of a vector in a particular direction. You will look at two ways of doing this: by drawing and by calculation (using trigonometry).

They require a good understanding of physics and more advanced reasoning skills. If you find the precious problems too easy, you may want to try the Jedi problems. They will probably be more interesting to you. Students who make a habit of solving Jedi problems successfully can request a placement in AP Physics next year.

Let in figure (a), the force on mass A because of mass B has a magnitude FB and is pointing towards mass B. Hence this force vector is making an angle o f 30° with the downward direction. Also, suppose the force on mass A because of mass C is Fc. This force is pointing towards mass C and is oriented at an angle of 30° with the downward direction.

21.14. Identify: Apply Coulomb’s law and find the vector sum of the two forces on Q. Set Up: The force that exerts on Q is repulsive, as in Example 21.4, but now the force that exerts is attractive. Execute: The x-components cancel. We only need the y-components, and each charge contributes equally. Therefore, the total force is in the .
