Horizontal Projectiles

Front

What is the formula for calculating the horizontal distance traveled by a projectile?

Back

Horizontal distance = horizontal velocity × time

Front

What is the acceleration due to gravity acting on a projectile in free fall?

Back

-9.81 m/s² (approximately -10 m/s² for simplification)

Front

How does the horizontal motion of a projectile differ from its vertical motion?

Back

Horizontal motion is at constant velocity, while vertical motion is accelerated due to gravity.

Front

What is the initial vertical speed of a projectile launched horizontally?

Back

0 m/s

Front

If a projectile is launched horizontally, what is its vertical displacement after 2 seconds?

Back

Vertical displacement = 0.5 × g × t² = 0.5 × 10 m/s² × (2 s)² = 20 m downward

Front

What factors affect the time a projectile remains in the air?

Back

The height from which it is launched and the acceleration due to gravity.

Front

What is the relationship between time of flight and horizontal distance for a projectile?

Back

Time of flight is independent of horizontal distance; it depends only on the initial height and gravity.

Front

How do you calculate the final velocity of a projectile after a certain time?

Back

Final velocity = initial velocity + (acceleration × time) for vertical motion.

Front

What is the significance of air resistance in projectile motion?

Back

Air resistance can reduce the horizontal distance and affect the trajectory of the projectile.

Front

What is the trajectory shape of a projectile launched horizontally?

Back

A parabolic path.
