Physics Vocabulary Crossword

2. A contact force that acts in the opposite direction of sliding or attempted sliding between two objects. Also includes moving through air or water.
6. The total energy an object has based on both Kinetic and Potential Energy. In an ideal Model, this total remains constant as the object moves.
9. The force that acts against pushing on a surface. Newton's 3rd law says all actions have equal and opposite reactions.
10. A push or pull on an object by another object that is touching it. Physical forces, normal force, friction, and tension are all examples.
11. The amount of energy stored in an object. The gravitational form is based on both height of the object and mass.
12. The product of how much force is used to move an object a certain distance. In an ideal Simple Machine, this total remains constant.
13. The force that acts against pulling on an object. Newton's 3rd law says all actions have equal and opposite reactions.
15. The energy and object has based on how quickly it is moving and how much mass the object has. Changing the speed has a greater affect than changing mass.

1. How much friction affects a simple machine. This number will be high if there is little friction, but low if there is lots of friction.
3. When 1 or more forces are acting on an object, which causes the object to accelerate in the direction of the net force.
4. Any change in motion caused by an unbalanced force. This can cause the object to speed up, slow down, and/or change direction.
5. A place, point, or object used to calculate the motion of another object.
7. When multiple forces are acting on an object, but they all cancel out so the object does not accelerate or change motion. Net Force = 0.
8. A push or a pull on one object by another object without them touching. Gravity and magnetism are both examples.
14. The distance traveled from a reference point divided by the time it took to travel (Distance ÷ Time).
