Exploring Projectile Motion in Physics

What is the only force acting on a projectile in ideal conditions?

• Magnetic force

• Friction

• Gravity

• Air resistance

What shape does the path of a projectile typically follow?

• Linear

• Circular

• Parabolic

• Elliptical

If a projectile is launched and returns to the same height, how does the time to go up compare to the time to come down?

• It depends on the angle of launch

• Time to go up is longer

• They are equal

• Time to come down is longer

In projectile motion, how are the vertical and horizontal motions related?

• Horizontal motion affects vertical motion

• Vertical motion affects horizontal motion

• They are independent of each other

• They are dependent on each other

What is the horizontal acceleration of a projectile in ideal conditions?

• 0 m/s^2

• 9.81 m/s^2

• Depends on the initial velocity

• Depends on the angle of launch

Fred throws a baseball horizontally at 42 m/s from a height of 2 meters. What is the initial vertical velocity of the baseball?

• 0 m/s

• 2 m/s

• 9.81 m/s

• 42 m/s

When solving projectile motion problems, what is the one variable that can be the same for both vertical and horizontal motions?

• Velocity

• Acceleration

• Time

• Displacement

What angle should you launch a projectile to achieve the maximum range, assuming no air resistance?

• 30 degrees

• 60 degrees

• 90 degrees

• 45 degrees

Herman the human cannonball is launched at 30 degrees with an initial velocity of 26 m/s. What is the horizontal component of his initial velocity?

• 22.5 m/s

• 26 m/s

• 30 m/s

• 13 m/s

In the mini-lab challenge, what two measurements are you asked to find using kinematic equations?

• Horizontal velocity and distance traveled

• Height of the table and time of flight

• Time of flight and distance traveled

• Height of the table and horizontal velocity
