Projectile Motion Range Review 1

What property(ies) of projectile motion without air resistance did we use in obtaining the range equation? Select all that apply.

• Symmetry of trajectory

• Constant velocity in the horizontal (x) direction

• Constant acceleration in the vertical (y) direction

• Constant velocity in the vertical (y) direction

• Constant acceleration in the horizontal (x) direction

What forces act on a projectile AFTER it has been launched? Select all that are correct.

• Launch force

• The weight

• Normal force

• The force of gravity

• Inertia

• We used Newton’s 1st Law

• We used Newton’s Second Law

• The acceleration is -g in the x-direction (horizontal)

• The acceleration in the y-direction (vertical) is zero

• We used Newton’s 1st Law

• We used Newton’s Second Law

• The acceleration is -g in the y-direction (vertical)

• The acceleration in the y-direction (vertical) is zero

• There is one less variable to account for

• Time is not a relevant variable for projectile motion

• The acceleration is -g in the x-direction (horizontal)
