Force & Motion Jeopardy I’m Drawing a Blank! Sir Isaac New some ton ? Accelerate Or Get Outta My Way! Miss Alanious

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/s ²). Answer: Newton

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

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

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

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

Sir Isaac Newsometon? 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!”

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

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.

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/s 2 (meters per second, per second)? Answer: 200N

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.

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.

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

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

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) a)twice the distance to come to a stop b)more than twice the distance to come to a stop c)less than twice the distance to come to a stop d)the same distance to come to a stop. Answer: (b) more than twice the distance to come to a stop

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

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.

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

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

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

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