Exploring Projectile Motion Concepts

What factors affect the maximum height of a projectile?

• Weather conditions, projectile color, and launch location.

• Weight of the projectile, time of day, and wind direction.

• Initial velocity, launch angle, gravity, and air resistance.

• Type of material, size of the projectile, and temperature.

Explain the significance of the launch angle in projectile motion.

• The launch angle only influences the color of the projectile.

• A higher launch angle always results in a shorter range.

• The launch angle has no effect on the speed of the projectile.

• The launch angle significantly affects the trajectory, range, and height of a projectile in motion.

How does air resistance affect projectile motion?

• Air resistance only affects the speed of a projectile.

• Air resistance has no effect on projectile motion.

• Air resistance decreases the range and height of a projectile.

• Air resistance increases the range and height of a projectile.

Describe the trajectory of a projectile in two dimensions.

• The trajectory of a projectile is a straight line.

• The trajectory of a projectile in two dimensions is a parabolic path.

• The trajectory of a projectile is a zigzag pattern.

• The trajectory of a projectile is a circular path.

What is the relationship between initial velocity and maximum height?

• Higher initial velocity decreases maximum height.

• Higher initial velocity results in greater maximum height.

• Initial velocity has no effect on maximum height.

• Lower initial velocity leads to greater maximum height.

How can you calculate the vertical and horizontal components of a projectile's velocity?

• vx = v + θ, vy = v - θ

• vx = v * sin(θ), vy = v * cos(θ)

• vx = v * tan(θ), vy = v * sec(θ)

• vx = v * cos(θ), vy = v * sin(θ)

What is the effect of increasing the launch angle on the range of a projectile?

• Increasing the launch angle always increases the range.

• Increasing the launch angle decreases the range up to 90 degrees.

• The launch angle has no effect on the range.

• Increasing the launch angle initially increases the range, then decreases it after 45 degrees.

How does the mass of a projectile influence its motion?

• The mass of a projectile affects its speed but not its trajectory.

• The mass of a projectile has no effect on its motion in a vacuum.

• A heavier projectile will always travel further than a lighter one.

• The mass of a projectile affects its motion only when air resistance is considered.

What role does gravity play in the motion of a projectile?

• Gravity only affects the horizontal motion of a projectile.

• Gravity acts as a constant force that accelerates the projectile downward.

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

• Gravity increases the maximum height of a projectile.
