- Newton Law 3
- a fish swimming forward
- friction
- this force slows down all moving objects
- reaction
- a force that is opposite to an action
- Newton Law 1
- an object in motion will stay in motion until a force stops it. An object at rest will stay at rest unless acted upon by a force.
- Newton Law 2
- you have to pedal harder to accelerate a bike to top speed in 5 seconds than to do the same in 2 minutes
- unbalanced forces
- when there is movement there are
- Newton Law 2
- You swing the baseball bat and hit the ball. It doesn't go as far as when the older boys hit the ball.
- Newton Law 3
- a wheel in motion
- Newton Law 3
- a game of marbles
- friction
- the force that opposes motion
- scientific law
- a theory that was tested many times and the results were always the same
- kilograms
- a unit of measure used to measure mass
- scale
- a device used to measure weight
- acceleration
- this means that something is speeding up
- average speed
- refers to the distance and time of an entire trip
- Newton Law 2
- You are helping your teacher build a rock garden during recess. You are pushing a wheelbarrow full of rocks and then dump them. Pushing the wheelbarrow back to school is much easier.
- Newton Law 1
- the moon orbiting the Earth
- gravity
- a force that every object in the universe exerts on every other object
- Newton
- a unit of measure used to measure weight
- Newton Law 1
- dislodging ketchup
- unbalanced forces
- when you step into quicksand, there are
- acceleration
- this means that something is slowing down
- balanced forces
- when there is no movement, there are
- Newton Law 3
- when a bird flies upward
- Newton Law 2
- Force = Mass x Acceleration
- Newton Law 2
- You are pushing a wheelbarrow full of rocks and then dump them. Pushing the wheelbarrow is now much easier.
- Newton Law 2
- why the bowling ball and the apple hit the ground at the same time when they are dropped from the same distance and at the same time
- Newton Law 2
- When a golfer needs to hit a long distance, he uses a driver rather than an iron.
- Newton Law 1
- why we should wear seat belts
- Newton Law 3
- You are in the school swimming pool gripping the edge. You push off the wall with your feet and shoot forward in the water.
- Newton Law 1
- You are playing a game of pool. You shoot one ball into another. The one you hit stops, but the one it hits moves into the side pocket.
- weight
- the measure of how much Earth's gravity pulls down on an object
- Newton Law 1
- You are standing on the merry-go-round waiting for someone to push it. When it does get pushed, you fall backward.
- Newton Law 2
- A=F/M
- Newton Law 1
- inertia
- mass
- the amount of material in an object
- Newton Law 3
- For every action there is an equal and opposite reaction
- force
- any push or pull on an object
- balance
- a device used to measure mass
- inertia
- resistance to a change in movement
- Newton Law 3
- a ride on a swing
- Newton Law 1, 3
- You are playing marbles. You shoot one into another. The one you hit stops, but the one it hits moves out of the circle.
- friction
- the brakes on a bicycle work by using
