Understanding Projectile Motion

What is the range of a projectile launched at an angle?

• R = (v^2 * sin(θ)) / g

• R = (v * cos(θ)) / g

• R = (v^2 * sin(2θ)) / g

• R = (v^2 * tan(θ)) / g

How does the initial velocity affect the time of flight?

• Lower initial velocity increases the time of flight.

• Higher initial velocity decreases the time of flight.

• Initial velocity has no effect on the time of flight.

• Higher initial velocity increases the time of flight.

What is the maximum height reached by a projectile?

• H = (v^2 * cos^2(θ)) / (2 * g)

• H = (v * sin(θ)) / g

• H = (v^2 * tan(θ)) / g

• H = (v^2 * sin^2(θ)) / (2 * g)

Explain the components of projectile motion.

• Projectile motion has no horizontal component.

• The components of projectile motion are horizontal motion (uniform) and vertical motion (accelerated due to gravity).

• Projectile motion is only affected by air resistance.

• Only vertical motion is considered in projectile motion.

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

• Range = (initial velocity * sin(θ)) * time of flight

• Range = (initial velocity * tan(θ)) * time of flight

• Range = (initial velocity * cos(θ)) * time of flight

• Range = (initial velocity * θ) * time of flight

What role does gravity play in projectile motion?

• Gravity only affects the horizontal motion of the projectile.

• Gravity causes the projectile to follow a curved path and accelerates it downward.

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

• Gravity causes the projectile to move in a straight line.

If a projectile is launched at 30 degrees, what is the vertical component of its velocity?

• 0.87 * initial velocity

• 0.25 * initial velocity

• initial velocity

• 0.5 * initial velocity

How does air resistance affect projectile motion?

• Air resistance decreases the range and alters the trajectory of a projectile.

• Air resistance increases the speed of a projectile.

• Air resistance has no effect on the trajectory of a projectile.

• Air resistance only affects the weight of the projectile.

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

• T = (2 * V₀ * sin(θ)) / g

• T = (V₀ * cos(θ)) / g

• T = (V₀ * sin(θ)) / (2 * g)

• T = (V₀ * tan(θ)) / g

Describe the trajectory of a projectile in two dimensions.

• The trajectory of a projectile is an ellipse.

• The trajectory of a projectile is a circle.

• The trajectory of a projectile is a straight line.

• The trajectory of a projectile in two dimensions is a parabola.
