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, while vertical motion is influenced by gravity.

Front

What is the acceleration due to gravity?

Back

The acceleration due to gravity is approximately 9.8 m/s² downward.

Front

What happens to the vertical velocity of a projectile at its highest point?

Back

At its highest point, the vertical velocity of a projectile is zero.

Front

What is the horizontal velocity of a projectile at its highest point?

Back

The horizontal velocity of a projectile remains constant throughout its flight, including at its highest point.

Front

How does air resistance affect projectile motion?

Back

Air resistance opposes the motion of the projectile, reducing its range and altering its trajectory.

Front

What is the formula for the range of a projectile?

Back

The range R of a projectile launched at an angle θ with initial velocity v₀ is given by R = (v₀² * sin(2θ)) / g, where g is the acceleration due to gravity.

Front

What is the time of flight for a projectile launched vertically?

Back

The time of flight T for a projectile launched vertically with initial velocity v₀ is T = (2 * v₀) / g.

Front

What is the maximum height of a projectile?

Back

The maximum height H of a projectile launched at an angle θ with initial velocity v₀ is given by H = (v₀² * sin²(θ)) / (2g).

Front

What is the effect of increasing the launch angle on the range of a projectile?

Back

Increasing the launch angle increases the maximum height but decreases the range, with the optimal angle for maximum range being 45 degrees.
