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.

Front

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

Back

The initial vertical speed of a projectile launched horizontally is 0 m/s.

Front

How do you calculate the time it takes for a projectile to hit the ground when dropped from a height?

Back

Use the formula: t = √(2h/g), where h is the height and g is the acceleration due to gravity (approximately 9.81 m/s²).

Front

What is the formula for the vertical component of velocity in projectile motion?

Back

The vertical component of velocity (Vy) can be calculated using: Vy = V * sin(θ), where V is the total velocity and θ is the launch angle.

Front

What is the formula for the horizontal component of velocity in projectile motion?

Back

The horizontal component of velocity (Vx) can be calculated using: Vx = V * cos(θ), where V is the total velocity and θ is the launch angle.

Front

What factors affect the range of a projectile?

Back

The range of a projectile is affected by its initial velocity, launch angle, and the height from which it is launched.

Front

What is the effect of air resistance on horizontal projectiles?

Back

Air resistance slows down the horizontal motion of projectiles, reducing their range and altering their trajectory.

Front

How does gravity affect a horizontally launched projectile?

Back

Gravity acts downward on the projectile, causing it to accelerate downward at 9.81 m/s², resulting in a parabolic trajectory.

Front

What is the total time of flight for a projectile launched at an angle?

Back

The total time of flight can be calculated using: t = (2 * Vy_initial) / g, where Vy_initial is the initial vertical velocity.

Front

What is the significance of the launch angle in projectile motion?

Back

The launch angle determines the initial vertical and horizontal components of velocity, affecting the height and distance traveled by the projectile.
