Back

36.25 m/s

Front

For horizontal projectile motion, the initial velocity in the y direction is equal to:

Back

0 m/s

Front

The path a projectile follows is known as:

Trajectory

Front

What is the optimal angle for maximum range in projectile motion?

Back

45 degrees

Front

The horizontal distance a projectile travels is known as:

Back

Range

Front

What is the formula for calculating the range of a projectile?

Back

Range = (v^2 * sin(2θ)) / g

Front

What does 'g' represent in projectile motion equations?

Back

Acceleration due to gravity, approximately 9.8 m/s².

Front

In projectile motion, what remains constant in the horizontal direction?

Back

Horizontal velocity.

Front

What is the effect of air resistance on projectile motion?

Back

It reduces the range and alters the trajectory.

Front

What is the vertical component of velocity at the peak of a projectile's trajectory?

Back

0 m/s.
