True: Speed measures how far something travels in a certain amount of time., Speed can be calculated by dividing distance by time., An object traveling 10 meters in 2 seconds is going 5 m/s., A pumpkin sitting still in a catapult is being held still by balanced forces., If a biker’s speed goes from 4 m/s to 8 m/s, the biker accelerated., velocity is speed in a specific direction, False: If an object’s speed is changing, it's at a constant speed., Balanced forces cause a change in motion., Gravity does not affect the motion of a launched pumpkin., A moving object will stop the second the force (that caused it to move) goes away, If an object changes direction, it is NOT accelerating,
