Concepts

3. ● Scalar quantity is a quantity that only has
magnitude.
● Friction is the force created when an object rubs or
moves against another object or its the force that
opposes motion.
Concepts

4. ● Density=Mass/Volume
● Normal Forces=9.8m/s^2
● Speed=Distance/Time
● Velocity=Speed + Direction
● Acceleration= Change in velocity(final -
initial velocity)/Time
● Converting Force= 1Kg=9.8N
