AP Physics Projectiles - 2D Motion (with Explanations)

Front

What variable is shared between the x and y directions in two-dimensional motion?

Back

Time is the variable that is shared between the x and y directions in two-dimensional motion.

Front

What is the horizontal acceleration of a projectile?

Back

The horizontal acceleration of a projectile is 0 m/s².

Front

What is the vertical acceleration of a projectile during its flight?

Back

The vertical acceleration of a projectile is -9.8 m/s² due to gravity.

Front

How do you calculate the horizontal component of velocity?

Back

The horizontal component of velocity can be calculated using the formula: Vx = V * cos(θ), where V is the initial velocity and θ is the launch angle.

Front

How do you calculate the vertical component of velocity?

Back

The vertical component of velocity can be calculated using the formula: Vy = V * sin(θ), where V is the initial velocity and θ is the launch angle.

Front

What is the formula for the maximum height of a projectile?

Back

The maximum height (H) can be calculated using the formula: H = (Vy²) / (2g), where Vy is the initial vertical velocity and g is the acceleration due to gravity.

Front

What is the range of a projectile?

Back

The range of a projectile is the horizontal distance it travels before landing, calculated using the formula: R = (Vx * t), where Vx is the horizontal velocity and t is the total time of flight.

Front

What is the time of flight for a projectile launched at an angle?

Back

The time of flight (t) can be calculated using the formula: t = (2 * Vy) / g, where Vy is the initial vertical velocity and g is the acceleration due to gravity.

Front

What is the effect of air resistance on projectile motion?

Back

Air resistance acts opposite to the direction of motion, reducing the range and maximum height of the projectile.

Front

What is the trajectory of a projectile?

Back

The trajectory of a projectile is the curved path it follows under the influence of gravity and its initial velocity.
