Question | Answer |
---|---|
What is speeding up, slowing down, or changing direction? | Acceleration |
How do you calculate net force if two forces are going in the SAME direction? | Add the forces |
How can an object that is not in motion be described? | At rest |
What kind of forces are acting when an object is at rest or it's moving in a straight line at a constant speed? | Balanced forces |
What is speed with direction? | Velocity |
