Projectile motion Flashcard

Front

What is the acceleration of a baseball at its highest point when thrown straight up?

Back

-10 m/s²

Front

What is the horizontal displacement of a football kicked off a 13.5 m high hill that lands 19.0 m away?

Back

19.0 m

Front

What variable letter represents horizontal velocity?

Back

Vₓ

Front

How does the initial vertical velocity of a dropped ball compare to its final vertical velocity just before hitting the ground?

Back

The final is greater.

Front

True or False: The more mass an object has, the faster it will fall (neglecting air resistance).

Back

False.

Front

Define projectile motion.

Back

Projectile motion is the motion of an object thrown into the air, subject to gravitational acceleration and air resistance.

Front

What is the formula for the range of a projectile?

Back

Range = (V₀² * sin(2θ)) / g, where V₀ is the initial velocity, θ is the launch angle, and g is the acceleration due to gravity.

Front

What is the effect of air resistance on projectile motion?

Back

Air resistance opposes the motion of the projectile, reducing its range and altering its trajectory.

Front

What is the vertical acceleration of a projectile in motion?

Back

-9.81 m/s² (due to gravity).

Front

What is the significance of the launch angle in projectile motion?

Back

The launch angle determines the shape of the projectile's trajectory and affects the range and height.
