Projectile Motion

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

• 0 m/s

• 9.81 m/s

• 5 m/s

• 15 m/s

What is the effect of gravity on a projectile's vertical motion?

• Gravity causes a downward acceleration, affecting the vertical velocity and position over time.

• Gravity has no effect on the vertical motion of a projectile.

• Gravity causes an upward acceleration, increasing the vertical velocity over time.

• Gravity only affects the horizontal motion of a projectile.

What is the range of a projectile?

• The maximum height reached by the projectile.

• The total time the projectile is in the air.

• The horizontal distance traveled when it returns to the same vertical level.

• The initial velocity of the projectile.

The shape of the path a projectile follows is...

• circular

• elliptical

• parabolic

• linear

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

• t = √(2h/g)

• t = h/g

• t = g/h

• t = 2h/g

What is the relationship between launch angle and range?

• The optimal launch angle for maximum range is 30 degrees.

• The optimal launch angle for maximum range is 45 degrees.

• The optimal launch angle for maximum range is 60 degrees.

• The optimal launch angle for maximum range is 75 degrees.

What is the significance of the initial velocity in projectile motion?

• It determines the range, height, and time of flight of the projectile.

• It only affects the height of the projectile.

• It has no effect on the projectile's motion.

• It determines the color of the projectile's path.

What factors affect the range of a projectile?

• Initial velocity, launch angle, and height of launch.

• Mass of the projectile, air resistance, and temperature.

• Color of the projectile, wind direction, and humidity.

• Shape of the projectile, surface area, and launch speed.

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

• Range = V_x * t, where V_x is horizontal velocity and t is time of flight.

• Range = V_y * t, where V_y is vertical velocity and t is time of flight.

• Range = V * sin(θ) * t, where V is initial velocity and θ is launch angle.

• Range = V * cos(θ) * t, where V is initial velocity and θ is launch angle.

Projectile Motion is motion in _____ dimensions.

• One (1D)

• Two (2D)

• Three (3D)

• Four (4D)
