$100 Newton’s 1 st Law Unless an object at rest is acted upon by an unbalanced force, it stays at rest due to its ________

$100 Answer Newton’s 1 st Law Inertia

$200 Newton’s 1 st Law What are the differences in how balanced and unbalanced forces affect motion?

$200 Answer Newton’s 1 st Law Balanced forces = no motion Unbalanced forces = motion

$300 Newton’s 1 st Law In physics, diagrams often use arrows to symbolize? Long Arrow = ?

$300 Answer Newton’s 1 st Law Arrows symbolize amount of force Long arrow = large force

$400 Newton’s 1 st Law Explain why you can spin an uncooked egg, stop it, yet it still spins (in terms on inertia)

$400 Answer Newton’s 1 st Law The yolk inside the egg is still spinning

$500 Question Newton’s 1 st Law Two children who are fighting over a toy pull on it from opposite sides. The result is a standoff. Explain this in terms of the net force

$500 Answer Newton’s 1 st Law Because the toy is not moving the children must be pulling with the same amount of force therefore net force = 0

$200 Answer Newton’s 2 nd Law Accelerate faster

$300 Question Newton’s 2 nd Law Mr. Keady rented a zip car to impress his female date. The car had a mass of 2000 kg and was able to produce 5000 N of force. How fast will he be able to accelerate?

$300 Answer Newton’s 2 nd Law 2.5 m/s2

$400 Question Newton’s 2 nd Law The unit of force, a newton, Is equal to what combination Of units

$400 Answer Newton’s 2 nd Law Kg x m/s2

$500 Question Newton’s 2 nd Law Mrs. Fine has a car that accelerates at 5 m/s2. If the car has a mass of 1000 kg, how much force does the car produce? However, now she wants to accelerate faster so she removes 500 kg from her car and uses the same force. How fast will she accelerate now?
