• Motion in three dimensions

In two-dimensional motion, which directions can an object travel?

• Length, height, and width

• Length and height

• Height and width

• Length and width

What force constantly accelerates an object downward on Earth?

• Friction

• Magnetism

• Gravity

• Air resistance

What is the acceleration due to gravity on Earth?

• 9.8 meters per minute squared

• 9.8 meters per second

• 9.8 meters per second squared

• 9.8 meters per minute

Which equation is used to solve for an unknown in the horizontal direction?

• Displacement = initial velocity * time + 1/2 * acceleration * time squared

• Final velocity squared = initial velocity squared + 2 * acceleration * displacement

• Final velocity = initial velocity + acceleration * time

• Velocity = distance / time

What is the term for the amount of time a projectile spends in the air?

• Hang time

• Drop time

• Flight time

• Air time

What is the initial vertical velocity of a horizontally launched projectile?

• Depends on the height

• 0 meters per second

• Equal to its horizontal velocity

• 9.8 meters per second

How do horizontal and vertical motions of a projectile relate to each other?

• They are dependent on each other

• They are the same

• They are independent of each other

• They affect each other
