word problem
If object A exerts a force on object B, then object B ?
also exerts an equal force on object A
newtons first law states that ?
an object at rest will remain at rest, an object in motion will remain at motion.
Newton is a unit used to measure ?
Force
what is inertia ?
An object at rest will stay at arrest and an object in motion will stay in motion and constant velocity unless acted upon by an unbalanced force.
Ms. Handahl, 26 (Not 36 Muriithi)
an 80 kg skier has a force of 200 N exerted on him down the slope. Calculate his acceleration down the slope. f=m x a
a =2.5 m/s-2
newtons third law states that for every action in nature there is ?
an equal and opposite reaction.
f=ma what does m mean ?
mass
Friction
A force that resists motion due to surfaces not being completely smooth
Does Ms. Handahl prefer fruity candy or chocolate?
Chocolate
If there is a net force not equal to 0 acting on an object what will happen?
accelerating/changing motion
How are inertia and mass related?
More mass= More inertia
Draw 2 pictures- 1 of an object experiencing balanced forces, and 1 experiencing unbalanced forces
Force
A push or a pull
What type of pet did Ms. Hinck have for 20 years?
A gecko
What does friction do?
Opposes Motion
In newtons second law:
Explain how amount of mass impacts acceleration
Explain how amount of force impacts acceleration
More mass=more acceleration
More force=more acceleration
what is the equation used in Newton's second law?
force equals mass times acceleration (F=MA)
Kinetic Energy
Energy from motion
What colors has Ms. May dyed her hair?
How much force would a football player exert if they have a mass of 100kg and an acceleration of 5m/s?
F=m xa
5 x 100= 500N of force
2 things acceleration depends on?
Force and mass
Draw a picture of newton's 3rd law. Include accurate vectors
Answer
Balanced and Unbalanced
Balanced: Net force=0
Unbalance: Net force= Not 0
What is Ms. Handahl's cat's full name? (she has 3 names)
Daisy Honey Bear
