You throw a dart up in the air, and it moves downward toward the dartboard. What force caused it to drop downward? | Gravity |
What Force pulls objects downward toward the earth? | Gravity |
You are pedaling your bike downhill. What causes your speed to increase? | Gravity |
Two kids are sitting on a seesaw the same distance apart and have the same mass. The seesaw is balanced. What will make the seesaw move? | One of the kids has to move forward or backward to create an unbalanced force? |
You kick a soccer ball across a grassy field. Eventually it comes to a rest. What force caused it to come to a stop? | Friction |
