4 cards from this section. Quick, good the night before a test.
What is the definition of resolution of velocity?
Think about how we analyze motion in two directions.
If a velocity vector is at 45° with a magnitude of 10 m/s, what are its components?
Use trigonometric functions to find the components.
What does the resolution of velocity allow us to do?
Think about why we need to analyze each direction separately.
True or False: The horizontal component of a projectile's motion changes due to gravity.
Consider how gravity affects motion in different directions.
A cyclist travels at 25 m/s at an angle of 75°. Calculate both the x and y components of the cyclist’s velocity.
Break the problem into each axis using trig functions.
An object is launched from a hill at a speed of 70 m/s at an angle of 60°. Determine the components of the force acting against gravity.
Use the sine and cosine functions related to the given angle.
