Projectile Motion Quiz

What is the acceleration in the vertical direction for projectile motion?

• 0 m/s²

• 9.8 m/s²

• -9.8 m/s²

• Depends on the angle

Which of the following is true about horizontal motion in projectile motion?

• It decelerates over time

• It has constant velocity

• It accelerates at 9.8 m/s²

How do you form the x-direction kinematic equations for projectile motion?

• By using only the final velocity

• By using only the original velocity

• By adding a subscript y to each variable

• By adding a subscript x to each variable

What trigonometric function is used to find the x-component of the original velocity?

• Cotangent

• Tangent

• Cosine

• Sine

In an angle launch projectile problem, what is typically given?

• Neither the original velocity nor the angle

• Only the angle of launch

• Only the original velocity

• Both the original velocity and angle of launch

What is the final y-velocity at the peak of a projectile's trajectory?

• Equal to the x-velocity

• Zero

• Equal to the initial y-velocity

• Negative of the initial y-velocity

What is the relationship between the time to reach the peak and the total time in the air for a projectile?

• Time to peak is equal to the total time

• Time to peak is double the total time

• Time to peak is half the total time

• Time to peak is unrelated to total time

Which equation is used to calculate the total horizontal displacement of a projectile?

• dy = vox * t

• dx = voy * t

• dy = voy * t

• dx = vox * t

What is the value of the horizontal acceleration (ax) in projectile motion?

• 0 m/s²

• -9.8 m/s²

• 9.8 m/s²

• Depends on the initial velocity

What must be done before using the original velocity in kinematic equations?

• Resolve it into x and y components

• Add it to the final velocity

• Convert it to meters per second

• Multiply it by the angle
