Projectile Motion Flashcard

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 are horizontal motion and vertical motion. Horizontal motion is uniform, while vertical motion is influenced by gravity.

Front

What is the significance of the vertical component of velocity (v_y) being zero?

Back

When v_y = 0 m/s, the projectile is at its highest point in the trajectory.

Front

How does initial velocity affect the range of a projectile?

Back

A higher initial velocity increases the range of the projectile, allowing it to travel farther horizontally before hitting the ground.

Front

What is the formula to calculate the time of flight for a projectile?

Back

The time of flight (T) can be calculated using the formula T = (2 * v_0 * sin(θ)) / 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 effect of air resistance on projectile motion?

Back

Air resistance opposes the motion of the projectile, reducing its range and altering its trajectory compared to ideal conditions without air resistance.

Front

What is the trajectory of a projectile?

Back

The trajectory of a projectile is the path it follows through space, typically a parabolic shape due to the influence of gravity.

Front

How do you calculate the horizontal distance traveled by a projectile?

Back

The horizontal distance (range) can be calculated using the formula R = v_0 * cos(θ) * T, where T is the time of flight.

Front

What happens to the horizontal component of velocity during projectile motion?

Back

The horizontal component of velocity remains constant throughout the motion, as there are no horizontal forces acting on the projectile (ignoring air resistance).

Front

What is the relationship between launch angle and range?

Back

The range of a projectile is maximized at a launch angle of 45 degrees, assuming no air resistance.
