Horizontally Launched Projectiles

Front

What is a horizontally launched projectile?

Back

A projectile that is launched with an initial horizontal velocity and is subject to gravitational acceleration, resulting in a parabolic trajectory.

Front

What is the effect of gravity on a horizontally launched projectile?

Back

Gravity only affects the vertical motion of the projectile, causing it to accelerate downwards at 9.8 m/s².

Front

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

Back

Time of flight (t) can be calculated using the formula t = √(2h/g), where h is the height and g is the acceleration due to gravity.

Front

How does the horizontal velocity of a projectile change during its flight?

Back

The horizontal velocity remains constant throughout the flight, as there are no horizontal forces acting on the projectile (ignoring air resistance).

Front

What is the relationship between vertical distance and time for a falling object?

Back

The vertical distance (d) fallen can be calculated using the formula d = 0.5gt², where g is the acceleration due to gravity.

Front

What is the significance of the initial vertical velocity in a horizontally launched projectile?

Back

The initial vertical velocity is zero for a horizontally launched projectile, meaning it starts falling from rest.

Front

How do you determine the final vertical velocity of a projectile just before it hits the ground?

Back

The final vertical velocity can be determined using the formula v = gt, where g is the acceleration due to gravity and t is the time of fall.

Front

What is the role of time in projectile motion?

Back

Time is the only variable that applies to both horizontal and vertical motion, allowing for the calculation of distances and velocities in both directions.

Front

What happens to the horizontal distance traveled by a projectile as time increases?

Back

The horizontal distance increases linearly with time, calculated using the formula d = vt, where v is the horizontal velocity.

Front

What is the acceleration of a projectile in the horizontal direction?

Back

The horizontal acceleration of a projectile is zero, as there are no forces acting in that direction (ignoring air resistance).
