True or False Ideal strings have no mass; therefor, they do not affect the acceleration of the system of objects

• True

• False

True or False ideal strings do stretch when exerting a force

• False

True or False Ideal strings exert only pulling forces and not pushing forces. A pushing force would crumple the string

• True

• False

True or False Ideal string forces are not exerted only in line with the string

• True

• False

The coefficient of friction is the same for each pair of materials.

• True

• False

Apparent weight is always equal to the actual weight

• True

• False

An accelerated reference frame is something slowing down

• True

• False

Examples of static friction: shoes rubbing when you walk, striking a match, soccer ball going in the goal

• False

• True

Rolling friction does not equal the sum total.
