Two surfaces rub as one slides on the other. The force that opposes that sliding is:Read the answer and worked solution →A person tries to walk on smooth ice and slips. What they are missing is:Read the answer and worked solution →A heavy crate sits still while a worker leans on it. The friction acting is:Read the answer and worked solution →A puck is already sliding across the ice. The friction slowing it is:Read the answer and worked solution →A box is hard to start moving but easier to keep moving. This shows static friction is:Read the answer and worked solution →A worker pushes gently on a fridge and it does not move. Static friction has:Read the answer and worked solution →The moment a stuck crate finally slides, static friction gives way to:Read the answer and worked solution →Even two mirror smooth plates still show friction. That is because of forces between their:Read the answer and worked solution →One common cause of friction is that surfaces are not perfectly:Read the answer and worked solution →Frictional force is described in how many forms, static and kinetic?Read the answer and worked solution →A block creeps along very slowly. At small but nonzero speeds friction is nearly:Read the answer and worked solution →A barge is dragged through water and the water pushes back. That fluid force is:Read the answer and worked solution →A plane flies forward through still air. The drag force acts:Read the answer and worked solution →A cyclist doubles her speed. Because drag goes as the square, it becomes about:Read the answer and worked solution →A skydiver stops speeding up and falls steadily. At that point drag equals his:Read the answer and worked solution →A 75 kg skydiver dives head first to cut his frontal area. His terminal speed is about:Read the answer and worked solution →A parachute opens above a falling jumper. The terminal velocity then becomes much:Read the answer and worked solution →A car turns a steady circle. The net force keeping it on that path is called:Read the answer and worked solution →A centripetal force always points toward the:Read the answer and worked solution →A car on a flat road rounds a bend without skidding. The centripetal force comes from:Read the answer and worked solution →A race track slopes its curves inward. That design is called a:Read the answer and worked solution →Catch the resisting forcesRead the answer and worked solution →Pop the drag raisersRead the answer and worked solution →Run the friction gatesRead the answer and worked solution →Slice the force wordsRead the answer and worked solution →At rest or in motionRead the answer and worked solution →Sort the force ideasRead the answer and worked solution →Type the numberRead the answer and worked solution →Friction and drag bingoRead the answer and worked solution →

Worked practice questions

Two surfaces rub as one slides on the other. The force that opposes that sliding is:

  1. Friction
  2. Fraction
  3. Fixation
  4. Flotation
Show answer and solution

Correct answer: A. Friction

1. Something resists the relative movement. 2. It acts where the two surfaces touch. 3. That force is friction. _Source: OpenStax University Physics Volume 1, Chapter 6, Applications of Newton's Laws._

A person tries to walk on smooth ice and slips. What they are missing is:

  1. Flotation
  2. Friction
  3. Fraction
  4. Fixation
Show answer and solution

Correct answer: B. Friction

1. Walking needs the ground to grip the shoe. 2. Ice gives very little grip. 3. So friction is what is missing. _Source: OpenStax University Physics Volume 1, Chapter 6, Applications of Newton's Laws._

A heavy crate sits still while a worker leans on it. The friction acting is:

  1. Static
  2. Stagnant
  3. Standard
  4. Straight
Show answer and solution

Correct answer: A. Static

1. Nothing is moving relative to the floor. 2. Friction still opposes the attempted push. 3. That is static friction. _Source: OpenStax University Physics Volume 1, Chapter 6, Applications of Newton's Laws._
