DES 5th Grade Force

Force

100

A push or a pull

What is Force

200

Newton's First Law

Inertia - an object at rest will remain at rest or an object in motion will remain in motion until acted on by an outside force

300

Newton's 2nd Law

F=MA

400

Newton's 3rd Law 

For every action there is an equal but opposite reaction

500

these are the two types of force keeping you on the ground while on Earth

Gravity and up thrust

Force 2

100

An object has a gravitation pull of 45N and an up thrust of 5N. Which direction will it move, Up towards the sky or down to the Earth?

Down to the Earth - pull is stronger than up thrust.

200

Two kids are on a swing. Each is pushed with 5N of force. One kid has a mass of 35kg and the other has a mass of 50kg. Which kid will move slower?

50Kg will accelerate slower

300

you roll a marble at 5 m/s. One surface is a tile floor and the other is carpet. On which surface will the marble roll farther?

tile

400

You are pushing a book case full of books with 45N of force. Half way you unload the books and continue pushing with the same force. What will happen to the bookcase when you push it the second time?

it will accelerate faster

500

this is speed with direction

velocity

words

100

this is the distance moved of an object over time or x=d/t

speed

200

this equals mass times acceleration x=MA

Force = MA or F=MA

300

the particles that make things up

matter

400

this produces heat when two objects slide past each other

Friction

500

this increases when direction is changed even if speed does not

acceleration 

misc

100

the larger the mass the ______ the force needed to move it

larger

200

magnets with the same poles will do what?

repel 

300

What is force?

a push or pull

400

when force is balanced an object will _______

not move

500

this equals a change in velocity over time

acceleration

balanced or unbalanced

100

An unbalanced force of 60N is pushing an object. will the object move towards you or away?

away

200

your team is pulling with 100N and the other team tugs with 90N. Will your team win or lose?

win

300

Car A is moving at 40 MPH hits  car B moving at 40 MPH. Will the cars move towards A, B, or neither?

neither

400

you throw a tennis ball at the wall at 45 mph. What will happen when it hits the wall? Will it fall straight down, bounce off with equal force, or stick to the wall?

bounce off with equal force

500

you jump out of an airplane with a parachute and fall towards the ground. What force keeps you from splattering on the ground? 

up thrust
