All Flashcards
Label the components of initial velocity in projectile motion.
1: v₀ (Initial Velocity), 2: v₀ * cos(θ) (Horizontal Component), 3: v₀ * sin(θ) (Vertical Component), 4: θ (Launch Angle)
Label the forces acting on a projectile during its motion (ignoring air resistance).
1: Force of Gravity (downwards)
What is the effect of gravity on the vertical velocity of a projectile?
Causes the vertical velocity to decrease as the object rises and increase as it falls.
What happens when the vertical velocity (v_y) is zero in projectile motion?
The projectile reaches its maximum height.
What is the effect of increasing the launch angle (θ) on the range of a projectile (given constant initial speed)?
Increases the range up to a maximum at 45 degrees, then decreases it.
What is the effect of increasing initial velocity on range?
Range increases.
What happens to the horizontal velocity of a projectile (ignoring air resistance)?
It remains constant throughout the motion.
Define projectile motion.
The path of an object launched into the air, influenced only by gravity.
What is a trajectory?
The curved path a projectile follows.
Define initial velocity (v₀).
The launch velocity that determines the trajectory's shape.
What is horizontal velocity (v_x) in projectile motion?
The velocity component that remains constant throughout the motion (assuming no air resistance).
What is vertical velocity (v_y) in projectile motion?
The velocity component that changes due to gravity.
Define 'g' in the context of projectile motion.
Acceleration due to gravity (approximately 9.8 m/s²).
