Across
- 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.
Down
- 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 รท Time).
