Projectile Motion

Front

What is projectile motion?

Back

Projectile motion is the motion of an object thrown into the air, subject to the force of gravity, following a curved path called a trajectory.

Front

What are the two components of projectile motion?

Back

The two components are horizontal motion (v_x) and vertical motion (v_y).

Front

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

Back

The acceleration in the horizontal direction is zero (0 m/s²) if air resistance is negligible.

Front

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

Back

The acceleration in the vertical direction is equal to the acceleration due to gravity, approximately -9.81 m/s².

Front

At the highest point of a projectile's path, what is the vertical velocity?

Back

The vertical velocity (v_y) at the highest point is zero (0 m/s).

Front

What is the range of a projectile?

Back

The range is the horizontal distance traveled by the projectile when it returns to the same vertical level from which it was launched.

Front

What factors affect the range of a projectile?

Back

The range is affected by the initial velocity, launch angle, and height of launch.

Front

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

Back

The time of flight (T) can be calculated using T = (2 * v_y_initial) / g, where g is the acceleration due to gravity.

Front

What is the launch angle that maximizes the range of a projectile?

Back

The launch angle that maximizes the range is 45 degrees.

Front

How does air resistance affect projectile motion?

Back

Air resistance decreases the range and alters the trajectory of the projectile.
