This picture is an example of ...
What is "balanced forces"?
Associated with Newton's First Law; the natural tendency of objects in motion to stay in motion and objects at rest to stay at rest, unless a force causes its speed or direction to change.

A curved line on a distance-time graph means that the object is ...
What is "accelerating"?
Velocity accounts for the ______ and ________ of an object.
A mine cart moving at a constant speed around a turn in its track is an example of _______ forces acting on a train.
What is "unbalanced"?
Newton's First Law states that an object at rest will ______ and that an object in uniform motion will _____ unless acted on by an unbalanced force.
What is "rest" and "continue in its motion"?
The shortest distance from the initial to the final position (does not consider the path taken).
Assuming time is on the x-axis (seconds) and distance is on the y-axis (meters), calculate how far the object travels from its highest point to its lowest point. (Hint: each tick mark represents 2 meters).
What is "18 m"?
Michael goes on a run every morning at 9 km/h around a lake near his house. Michael's starting point and ending point are his house. Michael’s brother Caleb also goes on a run every morning at 7 km/h traveling westward. Who has a known velocity?
What is "Caleb"?

What is "an unbalanced force"?
A point or object - ideally a fixed point or stationary object - used to determine the position and motion of another object relative to it.
What is "reference point"?
