You want a projectile to fly as far as possible, at which angle should you launch it? We'll start with formulas for the initial velocity.
Figuring out the horizontal displacement for a projectile launched at an angle.
How to solve for the horizontal displacement when the projectile starts with a horizontal initial velocity. We also explain common mistakes people make when doing horizontally launched projectile problems.
Visualising position, velocity and acceleration in two-dimensions for projectile motion.
Visualising, adding and breaking down vectors in 2 dimensions.
Defining and comparing tension, weight, friction and normal forces using free body diagrams.
Determining how fast something will be traveling upon impact when it is released from a given height.
Plotting projectile displacement, acceleration, and velocity as a function of time.
There are many different processes and phenomena that emit electromagnetic radiation. Humans have taken advantage of many of these processes to develop technologies that use electromagnetic radiation.
Photoelectric materials emit electrons when they absorb light of a high-enough frequency.
