100
An object in motion will stay __________
In motion
100
Force = Mass x ___________
What is acceleration
100
Every action has an equal and opposite ____________
What is reaction
100
Speed can be defined as
Distance divided by time it takes to travel (i.e. miles per hour)
200
Each question in science must be
Specific and testable
200
An object at rest will stay at rest unless ____________
Acted upon by an unbalanced force
200
The greater the force, the greater the ____________
What is acceleration
200
The balloon speeds forward when let go because __________
What is the air is being pushed behind it
200
Velocity differs from time in that
Velocity takes direction into account as well
300
We need to do research because
We need to know what is already known about the topic
300
This force will stop an object in motion (i.e. the force acting when grass stops a soccer ball from rolling)
Friction
300
If a giant truck and a motorcycle were to race, which would win?
What is the motorcycle, due to less mass leading to a larger acceleration
300
The swimmer gets pushed forward in the water because _________________
He is pushing the water backwards with each stroke and being pushed forward by the water.
300
What force is acting upon us at all times, pushing us toward the center of the Earth?
Gravity!
400
We do research before we __________
Make a hypothesis
400
Due to the first law of motion, when a car hits a brick wall, the passenger will ________.
Fly forward out the window
400
If an unbalanced force acts upon an object, the object will _______________
Acceleration in the direction of that force
400
When a basketball goes down through a net, the net is pushed
What is up
400
In order to judge motion, we need a
Reference point
500
When we do an experiment and it turns out our hypothesis isn't correct, what do we do?
We change the hypothesis and re-do the experiment.
500
The idea of absolute rest is (correct or incorrect)
What is incorrect! No object can be absolutely at rest or absolutely in motion
500
If force = mass x acceleration, then mass =
What is force divided by acceleration
500
What happens when you push against a wall?
The wall pushes back against you.
500
The velocity divided by time =
Acceleration
