C - Projectile Motion

Front

What is projectile motion?

Back

Projectile motion is the motion of an object that is thrown into the air and is subject to the force of gravity. It follows a curved path called a trajectory.

Front

What are the two components of projectile motion?

Back

The two components of projectile motion are horizontal motion and vertical motion. Horizontal motion is uniform (constant velocity), while vertical motion is influenced by gravity.

Front

What is the acceleration of a projectile in the horizontal direction?

Back

The acceleration of a projectile in the horizontal direction (a_x) is zero, meaning there is no change in horizontal velocity.

Front

What is the acceleration of a projectile in the vertical direction?

Back

The acceleration of a projectile in the vertical direction (a_y) is equal to -g, where g is the acceleration due to gravity (approximately 9.81 m/s² downward).

Front

How does air resistance affect projectile motion?

Back

In ideal projectile motion, air resistance is neglected. However, in real scenarios, air resistance opposes the motion and can alter the trajectory.

Front

What is the time of flight for a projectile?

Back

The time of flight is the total time the projectile is in the air, determined by the initial vertical velocity and the height from which it is launched.

Front

What is the range of a projectile?

Back

The range of a projectile is the horizontal distance it travels before hitting the ground, dependent on the initial velocity and launch angle.

Front

What is the maximum height of a projectile?

Back

The maximum height is the highest vertical position reached by the projectile, determined by its initial vertical velocity and the effect of gravity.

Front

What is the formula for the horizontal distance traveled by a projectile?

Back

The formula for the horizontal distance (range) is R = (v_0^2 * sin(2θ)) / g, where v_0 is the initial velocity, θ is the launch angle, and g is the acceleration due to gravity.

Front

What is the formula for the vertical motion of a projectile?

Back

The vertical motion can be described by the equation: y = v_0sin(θ)t - (1/2)gt², where y is the vertical displacement, v_0 is the initial velocity, θ is the launch angle, and t is time.
