2 cards from this section. Quick, good the night before a test.
Define projectile motion.
Think about objects like thrown balls.
What is the horizontal range?
Consider the term 'range' in sports.
What is the primary force acting on a projectile during flight?
Think about natural forces affecting falling objects.
True or False: The horizontal component of velocity for a projectile is constant throughout its motion.
Consider how motion behaves without acceleration.
A ball is launched from the ground with an initial speed of 18 m/s at an angle of 60°. Calculate the maximum height and total time of flight.
Be careful with the sine values for 60°!
A rock is thrown off a cliff 50m high at a velocity of 20 m/s at a 30° angle. Calculate how far from the base of the cliff it lands.
For vertical motion, use the equation y = yo + voy * t - (1/2) g t². Solve for t first!
