Horizontal Projectiles

Front

What is a horizontal projectile?

Back

A horizontal projectile is an object that is launched into the air with an initial horizontal velocity and is subject to gravitational acceleration, causing it to follow a curved path until it hits the ground.

Front

What information is needed to find the time it takes for a horizontal projectile to fall?

Back

The height of the cliff or the vertical distance from which it is launched.

Front

What is the acceleration of a horizontal projectile in the vertical direction, assuming no air resistance?

Back

The acceleration is -10 m/s², which is due to gravity.

Front

If a projectile is launched horizontally, how does its horizontal velocity change over time?

Back

The horizontal velocity remains constant if we neglect air resistance.

Front

How do you calculate the horizontal distance traveled by a projectile?

Back

Horizontal distance = horizontal velocity × time of flight.

Front

What is the effect of air resistance on horizontal projectiles?

Back

Air resistance can decrease the horizontal distance traveled by a projectile and affect its velocity.

Front

If a cannonball is launched horizontally at 50 m/s from an 80 m tall cliff, how far will it go before hitting the ground?

Back

200 m.

Front

What is the formula to calculate the time of flight for a projectile launched horizontally?

Back

Time of flight = √(2h/g), where h is the height and g is the acceleration due to gravity (approximately 10 m/s²).

Front

What happens to the vertical velocity of a projectile as it falls?

Back

The vertical velocity increases due to the constant acceleration of gravity.

Front

If a ball is launched horizontally at 40 m/s, what will be its horizontal velocity after 3 seconds?

Back

40 m/s, as horizontal velocity remains constant.
