motion

1. time

1.1. Time is a measure in which events can be ordered from the past through the present into the future, and also the measure of duration of events and the intervals between them.

1.2. passing over time

1.3. sharpness

2. velocity

2.1. Velocity is the rate of change of the displacement, the difference between the final and initial position of an object.

2.2. going up

2.3. rate

3. gravity

3.1. Gravitation or gravity is a natural phenomenon by which all physical bodies attract each other.

3.2. something that float

3.3. weight

4. friction

4.1. Friction is the force resisting the relative motion of solid surfaces fluid layers and material elements sliding against each other.

4.2. two things robing together

4.3. friction

5. acceleration

5.1. Acceleration in physics is the rate of change of velocity of an object.

5.2. so far in seconds

5.3. spur

6. force

6.1. force is any interaction which tends to change the motion of an object.

6.2. how much a thing is pulling

6.3. strenght

7. speed

7.1. In everyday use and in kinematics, the speed of an object is the magnitude of its velocity the rate of change of its position it is thus a scalar quantity.

7.2. going so far in seconds

7.3. hurry

8. distance

8.1. Distance is a numerical description of how far apart objects are.

8.2. how far it is

8.3. withdraw
