Quantities with only a size/magnitude (ex: speed, mass, length,
temperature, time, distance, energy, etc.) Quiz____?Vectors - Answer✓✓
Quantities with both a size and direction (ex: displacement, velocity,
position, acceleration, force, etc.) Quiz____?Projectile Motion - Answer✓✓ -Horizontal and vertical components are independent of each other -Complementary angles travel same horizontal distance -Larger angles travel higher and spend more time in air, while smaller angles have greater horizontal velocities Quiz____?Force (F) - Answer✓✓ -A push or pull -Measured in Newtons (N) Quiz____?Newton's 1st Law - Answer✓✓ Page 3 of 20
