Projectile Motion: Freefall and 2D GHS

Front

What is the optimal release angle for achieving the greatest horizontal range in projectile motion?

Back

45°

Front

What is the acceleration in the y-component of projectile motion for an object thrown upward?

Back

-9.8 m/s²

Front

Which equation is used to calculate the horizontal component of velocity (Vx)?

Back

Vx = Vi * cos(θ)

Front

At which point in projectile motion is the vertical velocity (Vy) the largest?

Back

Point C (the highest point of the trajectory)

Front

What factor is typically ignored in projectile motion problems?

Back

Air resistance

Front

Define 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.

Front

What are the two components of projectile motion?

Back

Horizontal and vertical components.

Front

How does gravity affect the vertical motion of a projectile?

Back

Gravity causes a downward acceleration of -9.8 m/s².

Front

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

Back

Time of flight = (2 * Vi * sin(θ)) / g

Front

What is the range of a projectile?

Back

The horizontal distance traveled by the projectile.
