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

Front

What is the formula for calculating the time of flight for a projectile?

Back

Time of flight (t) can be calculated using the formula: t = (2 * initial vertical velocity) / g, where g is the acceleration due to gravity (approximately 9.81 m/s²).

Front

How does the angle of launch affect the range of a projectile?

Back

The angle of launch affects the range; a launch angle of 45° typically provides the maximum range for a given initial velocity.

Front

What is the horizontal velocity of a projectile?

Back

The horizontal velocity (vx) remains constant throughout the projectile's flight, as there are no horizontal forces acting on it (ignoring air resistance).

Front

What is the vertical velocity of a projectile at its peak height?

Back

At the peak height of its trajectory, the vertical velocity of a projectile is 0 m/s.

Front

How do you calculate the range of a projectile?

Back

The range (R) can be calculated using the formula: R = (initial velocity² * sin(2 * launch angle)) / g.

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 projectile motion.

Front

What is the significance of the initial velocity in projectile motion?

Back

The initial velocity determines how far and how high the projectile will travel. Both the magnitude and direction of the initial velocity are crucial.

Front

What is the trajectory of a projectile?

Back

The trajectory is the path that a projectile follows through space, typically a parabolic shape under the influence of gravity.
