unit for speed | m/s or km/hr |
unit for distance | meter, centimeters, millimeters, kilometers |
unit for time | seconds or hours |
m/s or km/hr | unit for speed |
meters, kilometers, centimeters, millimeters | unit for distance |
seconds or hours | unit for time |
force the pulls objects toward each other | gravity |
units for mass | grams |
kilograms or grams | units for mass |
distance and direction of object's change in position | displacement |
distance / time | speed |
speed does not vary or change | constant speed |
total distance /total time | average speed |
result of speedometer reading at a specific moment in time | instantaneous speed |
43.33 m/s | speed |
measurement from one point to the next | distance |
the resistance caused when one object is moved in contact with another | friction |
likely to maintain a state of rest unless acted upon by an external force | inertia |
do not change speed or direction | balanced forces |
resistance of fluid to flow | viscosity |
16.78 m | distance |
22.11 s | time |
89.55 km | distance |

the force resisting the motion when a body (such as a ball, tire, or wheel) rolls on a surface | rolling friction |
force that must be overcome for something to get going. | static friction |
frictional resistance to relative movement of surfaces on loaded contact | sliding friction |
friction arising between two objects in contact that are at rest with respect to each other. | static friction |
