Exploring Kinematic Equations in Two Dimensions

What is the path of a projectile after it is thrown?

• Parabolic

• Circular

• Straight line

• Elliptical

Which component of velocity remains constant throughout the projectile's flight?

• Both vertical and horizontal velocities

• Neither vertical nor horizontal velocities

• Vertical velocity

• Horizontal velocity

What is the acceleration acting on a projectile in the vertical direction?

• 15 m/s²

• 5 m/s²

• 9.81 m/s²

• 0 m/s²

Which kinematic equation describes the final vertical velocity of a projectile?

• Δx = v_0x t

• Δy = v_0y t + 0.5gt²

• v_x = v_0x + at

• v_y = v_0y + gt

What is the equation for the change in vertical position of a projectile?

• v_x = v_0x

• Δy = v_0y t + 0.5gt²

• Δx = v_0x t

• v_y = v_0y + gt

Why is there no acceleration in the horizontal direction for a projectile?

• Because gravity only acts vertically

• Because air resistance cancels it out

• Because the initial horizontal velocity is zero

• Because the horizontal velocity is always increasing

What is the horizontal displacement equation for a projectile?

• v_y = v_0y + gt

• v_x = v_0x + at

• Δy = v_0y t + 0.5gt²

• Δx = v_0x t

Which of the following is NOT a kinematic equation used for projectile motion?

• v_y = v_0y + gt

• Δx = v_0x t

• v_x = v_0x + gt

• Δy = v_0y t + 0.5gt²

How can we use the horizontal component to solve for time in projectile motion problems?

• By using the equation v_y = v_0y + gt

• By using the equation Δy = v_0y t + 0.5gt²

• By using the equation Δx = v_0x t

• By using the equation v_x = v_0x + at

What remains the same whether you are working horizontally or vertically in projectile motion?

• Displacement

• Velocity

• Time

• Acceleration
