Gravity
What is gravity?
a force that pulls objects down
What do we call a force that moves an object away?
A push
Name a force that needs contact
Friction or push
What are the two poles of a magnet?
North and South poles
What is mass?
the amount of matter in an object
What is the effect of gravity on weight?
The more gravity, the heavier an object feels.
What is a force that brings objects closer?
A pull
What is friction?
A force that slows down moving objects when two surfaces rub against each other
What happens when you bring two north poles together?
They repel each other
What is a force?
a push or pull that makes objects move
How does gravity affect falling objects?
Gravity pulls them down faster
Give an example of a push force (you can write this or act it out)
answers will vary
How does friction affect motion?
It can stop or slow things down
They attract each other
What is acceleration?
when something speeds up, slows down, or changes direction
What happens to gravity as you go higher?
Gravity gets weaker.
Give an example of a pull (you may write this or act it out)
answers will vary
Why is friction important in everyday life?
It helps us walk without slipping
What is the strongest part of a magnet?
The poles
What happens when two forces are balanced?
They do not move
Why is gravity important for life on Earth?
Because without it we would be floating and not on the ground.
How do pushes and pulls work together?
They can move objects in different directions.
What happens when two surfaces slide against each other?
It creates heat
What kind of force is magnetism?
A non contact force
Give an example of an unbalanced force (you may write this or act it out)
examples: tug of war, etc.
