Displacement (Δx) - ANSWER ✔✔-Net change in position
-Measured in meters (m)
Δx = x(f) - x(i)
Velocity (v) - ANSWER ✔✔-Speed and direction
-Measured in meters per second (m/s)
average v = Δx/t
Acceleration (a) - ANSWER ✔✔-Rate of change of velocity w/
respect to time
-Measured in meters per second squared (m/s^2)
average a = Δv/t
Speeding up vs. Slowing Down - ANSWER ✔✔-Speeding up occurs
when velocity and acceleration have the same sign
-Slowing down occurs when velocity and acceleration have opposite
signs
Position vs. Time Graph - ANSWER ✔✔-Slope represents average
velocity
, -Object changes direction when graph crosses x-axis
Velocity vs. Time Graph - ANSWER ✔✔-Slope represents average
acceleration
-Area represents displacement
Acceleration vs. Time Graph - ANSWER ✔✔-Area represents change
in velocity
Scalars - ANSWER ✔✔Quantities with only a size/magnitude (ex:
speed, mass, length, temperature, time, distance, energy, etc.)
Vectors - ANSWER ✔✔Quantities with both a size and direction (ex:
displacement, velocity, position, acceleration, force, etc.)
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
Force (F) - ANSWER ✔✔-A push or pull
-Measured in Newtons (N)
