use your notes from pages 11 - 12 and the terms in the vocabulary box to fill in the blanks for the following five questions. each term may be used more than once.

1. a(n) ____________ is a push or a pull that acts on an object.
2. ____________ forces only have an effect on objects that they touch.
3. ____________ forces act on an object without touching them.
4. __________ works to slow down or stop motion due to surfaces rubbing against each other. ________ force is experienced by a rope when it is pulled at either end. ________ force is exerted when a spring returns to its normal shape. these are examples of __________ forces.
5. a(n) __________ force pulls objects toward each other because they have mass. a(n) ________ force pulls or pushes on metals such as iron. a(n) ________ force causes pushing and pulling forces due to differences in charge of the small particles that make up matter. these are examples of __________ forces.

Explanation:

1. By definition, a force is a push or pull on an object.
2. Contact forces act on objects they touch.
3. Action - at - a - distance forces act without touching.
4. Friction slows motion due to rubbing, tension is in a pulled rope, elastic force is when a spring returns to shape, and these are contact forces.
5. Gravitational force acts on masses, magnetic force acts on metals like iron, electrostatic force is due to charge differences, and these are action - at - a - distance forces.

Answer:

1. Force
2. Contact
3. Action - at - a - distance
4. Friction; Tension; Elastic; Contact
5. Gravitational; Magnetic; Electrostatic; Action - at - a - distance
