How are the following terms related to the bowling ball activity :
Speed, velocity, acceleration, force, gravity, weight, inertia, and friction?

2. Force and Motion
SPS8. Students will determine relationships among force, mass, and motion.
a. Calculate velocity and acceleration.

3. Speed
A measure of how fast an object is traveling.
Speed = distance traveled / time taken
S = d/t

4. Speed
Example: The car you are riding in travels 140 miles in 2 hours. S = d/t S = 140 mi / 2 hr S = 70 mi/hr

5. Velocity
The speed and direction in which an object is moving.
v = d/t and direction

6. Velocity
Example:
Your car is traveling at a velocity of 70 mi/hr south.

7. Acceleration
The rate at which an object’s velocity (speed) is changing.
Acceleration = (final velocity – initial velocity) divided by time
a = (vf – vi) / t

8. Acceleration Example:
A jet flying at 125 m/s increases its velocity to 140 m/s in 10 s.
a = (vf – vi) / t
a = (140 m/s m/s) / 10s
a = 1.5 m/s/s
a = 1.5 m/s2

9. Force
Any push or pull that could cause a change in motion.
