Newton's First Law States that...

• F= ma

• Objects in motion will stay in motion

• Objects at rest will stay at rest unless acted upon by an external force

• Everything has an equal and opposite reaction

What is the acceleration of a 100kg object pushed by a force of 1000N? F=ma

• 11m/s^2

• None are Correct

• 10km/s

• 10m/s

What is the formula used to find Force?

• m=f x b

• f=b x z

• m=f x a

• f=m x a

If the force acing on a car doubles, what happens to the cart's acceleration?

• It quarters

• it stays the same

• it doubles

• it halves

What is the correct unit used to express acceleration?

• m/s

• m/s^2

• cm

• There are no units associated with acceleration

How can Newton's second law be represented mathematically?

• F = m x a

• m = f / a

• a = f / m

• All of the above

If and object is accelerating at 10m/s^2 and it weighs 10kg, what is the force required to move it?

a = 10 m/s^2

m = 10 kg

f = ?

• 0N

• 100N

• 20N

• 30N

Select the most relevant statement to describe Newton's Third Law

• All forces are the same

• Forces have reaction forces that are unequal

• For every force there is an equal and opposite force

• None of the above

• Test the hardness of water

• Test the acidity of water

• Test the alkalinity of water

• To rank solutions in terms of acidity or alkalinity

The pH scale ranges from ...

• 0-12

• 1-10

• 0-14

• 1-14
