2. MOTION AND FORCE
CHAPTER ONE

3. FRAME OF REFERENCE
The background or point that is used for
comparison when motion is described.
The most common frame of reference is the
Earth.

4. What is motion?
Motion is the change in position relative to the frame
of reference in a certain amount of time.

5. What is speed?
What is the formula for speed
Speed is the rate at which an object moves.
Speed = Distance
Time

6. A car travels 240 kilometers in 3
hours. What is the speed of the car
during that time?
80 km/hr

7. What is velocity?
Velocity is speed in a given direction.

8. What is acceleration?
What is the formula for
acceleration?
The rate of change in velocity is known as
acceleration.
Acceleration = final velocity – original velocity
time

9. A car is traveling at 60 km/hr. It
accelerates to 85 km/hr in 5
seconds. What is the acceleration
of the car?
18,000 kilometers/hour

10. Circular Motion
The velocity is continuously changing because direction is
continuously changing.
An object in circular motion is accelerating even though its
speed may be constant.

11. What is momentum?
Momentum is equal to the mass of an object multiplied
by its velocity
Momentum = Mass x Velocity

12. How is momentum conserved?
The total momentum of any group of objects remains the
same unless outside influences act on the objects.
