100
What are the units used for speed?
What is meters per second (m/s)
100
A set of forces that are NOT equal in size
What is unbalanced force
200
A ____________ variable is anything that is held constant in an experiment
What is control
200
What are the two words used to describe force?
What is push and pull
200
What is one way that mass is different than weight?
What is... different units (pounds vs grams), weight is dependent on gravity, mass is amount of matter in an object

What is fair test
300
A ____________ variable is what is measured as a result of the experiment
What is dependent
300
What is the net force and which direction is it pointing?
What is 50 Newtons to the left

I want Piglet to have the most amount of energy. Should I increase her food so she has more mass, or put her on a diet so she has less mass?
What is increase her food (more mass)
300
I want Piglet to be FAST. If I pull her with a force of 8 Newtons, how much would I want her mass to be so she accelerates the fastest?
1 kg
2 kg
4 kg
What is 1 kg
300
Which one of Newton's Laws states: "an object in motion will stay in motion and an object at rest will stay at rest unless an unbalanced force is applied"
What is Newton's 1st Law
400
I am trying to see what type of blanket Piglet sleeps the longest through the night with: fluffy, silky, or rough. What will I be measuring during this experiment and what type of variable is that?
What is hours of sleep and dependent
400
If Piglet is being pulled to the left with a force of 5 Newtons, how much force will need to be applied to achieve a net force of 0? What direction will that force need to be applied?
What is a pull force to the right of 5 N

If I kick a ball with a force of 20 Newtons and is accelerates at 5 m/s, what is the mass of the ball?
What is 4 kilograms (kg)
400
If I kick a ball with a force of 8 Newtons and the ball has a mass of 2 kg, how fast will it accelerate?
What is 4 meters per second (m/s)

I am trying to see what type of blanket Piglet sleeps the longest through the night with: fluffy, silky, or rough. What are 2 examples of control variables in this experiment?
What is room temperature, bed, dinner time, snuggles with Ms. Murphy, amount of blanket, location of blanket on the bed, and others approved by teacher
500
If the mass of a ball is 5kg and it accelerates at 10 m/s, how much force was applied when I kicked the ball?
What is 50 Newtons
