  1. Force & Motion Jeopardy

  2. I’m Drawing a Blank! 100 • The unit of measurement for force is a ___________. One of those units equals the amount of force needed to move 1Kg of mass 1 meter per second squared. • (N = 1Kg x 1 m/s²). • Answer: Newton

  3. I’m Drawing a Blank! 200 • A __________ ________ on a motion graph indicates that the object is at rest, or is not moving. • Answer: Horizontal line

  4. I’m Drawing a Blank! 300 • The force that exist between two objects’ surfaces is ______________, and it works against the direction of motion. • Answer: Friction

  5. I’m Drawing a Blank! 400 • Acceleration means changes in an object’s ______________ and/or ______________ of movement. • Answer: Speed and/or Direction

  6. I’m Drawing a Blank! 500 • The tendency of an object to resist changes in its motion is called_________? • Answer: Inertia

  7. Sir IsaacNewsometon? 100 • According to Newton’s “third law of motion,” do forces act alone or in pairs? • Answer: Forces act in pairs. For every “Action force,” there is an opposite and equal “Reaction force!”

  8. Sir Isaac Newsometon? 200 • Newton’s “first law of motion,” which states that an object’s motion will stay the same unless it is acted upon by other forces is also called the “Law of _____________.” • Answer: Inertia

  9. Sir Isaac Newsometon? 300 • If we know that the forces acting upon an object are balanced (Net Force = Zero), what do we know about the object’s motion? • Answer: The object’s motion is staying the same. It’s not changing. It’s not accelerating.

  10. Sir Isaac Newsometon? 400 • Using the formula F = m a, what force (in Newtons [N]) is required to accelerate a 100 Kg object 2 m/s2 (meters per second, per second)? • Answer: 200N

  11. Sir Isaac Newsometon? 500 • What is needed to change the direction or speed of an object’s motion? Or, what is needed to get the object to accelerate? • Answer: Unbalanced forces need to be acting upon it. Put another way, there needs to be a Non-Zero Net Force.

  12. Accelerate Or Getoutta My Way! 100 • If one van is loaded with 1 ton of lumber on its roof, and an identical one is loaded with 1 ton of lumber inside its cargo area, which one will be less stable going around a traffic circle and why? • Answer: The van loaded on its roof will be less stable because of its higher center of mass—it has a higher risk of rolling over.

  13. Accelerate Or Getoutta My Way! 200 • List four factors/variables that would affect a car’s stopping distance. (you need to be specific and not include similar/related factors) • Answer: • Driver alertness • Condition of brakes • Condition of tire tread • Road surface conditions • Speed of travel • The Mass of the car and its cargo • Shrek is the driver

  14. Accelerate Or Getoutta My Way! 300 • An SUV is more likely to experience a rollover accident than a small compact car because its “center of mass” is _________. • Answer: Higher

  15. Accelerate Or Getoutta My Way! 400 • (Multiple Choice) When one of two identical cars is traveling twice the speed of the other, it will take: (a, b, c, or d) • twice the distance to come to a stop • more than twice the distance to come to a stop • less than twice the distance to come to a stop • the same distance to come to a stop. • Answer: (b) more than twice the distance to come to a stop

  16. Accelerate Or Getoutta My Way! 500 • A car is ________________ if either its speed or direction changes. • Answer: Accelerating

  17. Miss Alanious 100 • In order to calculate the “speed” of an object’s motion, what two things do we need to know? • Answer: Distance traveled & Time.

  18. Miss Alanious 200 • Who was the British scientist that developed the three laws of motion and physics? • Answer: Sir Isaac Newton

  19. Miss Alanious 300 • If you know the distance an object has traveled, and the amount of time it took, what can you calculate or determine? • Answer: The object’s speed

  20. Miss Alanious 400 • What is the average speed of a person driving 300 miles in 4 hours? • Answer: 75 miles/h or 75 mph

  21. Miss Alanious 500 • The equation for force is __________ & what do the letters stand for? • Answer: F=M∙A (Force = Mass x Acceleration)
