2D Vectors and Motion

What is the advantage of using vectors to describe motion?

• They have a magnitude

• They have a direction

• They simplify calculations

• They are scalar numbers

How can vectors be represented graphically?

• As arrows

• As numbers

• As triangles

• As circles

How can vectors be added or subtracted?

• By multiplying their magnitudes

• By dividing their magnitudes

• By adding or subtracting their components

• By multiplying or dividing their components

What happens to the vertical and horizontal components of a vector when they are separated (resolved to component via trigonometry)?

• They become dependent on each other

• They become independent of each other

• They cancel each other out

• They combine to form a new vector

In a pitching machine (projectile motion), what mostly determines the time it takes for a ball to hit the ground?

• The horizontal velocity

• The vertical velocity

• The angle of launch only

• amount of air resistance

What is the vertical velocity of a ball at its highest point?

• Zero

• Positive

• Negative

• Equal to the horizontal velocity

What is the relationship between horizontal and vertical motion in a pitching machine?

• They are dependent on each other

• They are independent of each other

• They are inversely proportional

• They are directly proportional
