An object at rest will remain at rest and an object in motion will remain in motion unless acted on by an unbalanced force:
For every action force there is an equal and opposite reaction force:
Shows how force, mass, and acceleration are related; commonly shown with the formula F=ma
, The total distance an object travels divided by the total time
The tendency of still or moving object to resist changes in its motion:
.
1. Newton's first law of motion
2. Newton's third law of motion
3. Newton's second law of motion
4. Average speed
5. Inertia
Refer to the graph below to answer the following question: A group of students recorded the distances that four runners traveled in the span of 60 seconds.
What is the speed of Runner A at 10s? (*Hint: Trace the line back to the letter that labels the line to be sure you are looking at the correct line.)

To determine the speed of Runner A at 10 seconds, we trace a vertical line from the point at 10 seconds on the x-axis to the line labeled "A" on the graph that represents Runner A. Then, we read the corresponding value on the y-axis to find the speed.
Based on the graph provided, the speed of Runner A at 10s is 40 m/s.
Therefore, the correct answer is: 40 m/s
