True or False ideal strings do stretch when exerting a force

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

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

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

Apparent weight is always equal to the actual weight

An accelerated reference frame is something slowing down

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

Rolling friction does not equal the sum total.

Jersey barriers are made at an angle to force the car back onto the highway.

Kinetic force is what it takes to keep it moving.

The normal term in math means parallel.

Static force is what it takes to get it moving.

A characteristic of an ideal pulley is a grooved wheel

Apparent weight = real weight when the object being weighed is not accelerating.

A car parked on a hill is an example of static friction.

Jersey barriers are used to not deflect a car.

Friction is not a general force between two surfaces.

The force that acts on a car is static friction.

Friction allows rolling, walking, and braking.
