Balanced or Unbalanced
When a different amount of force is being applied from opposite directions. When an object speeds up, slows down, or changes direction.
What is an unbalanced force?
The two things needed to determine how much an object moves
What is mass and speed?
the thing you are measuring/observing in an experiment?
What is a dependent variable?
The things that are a need or a must have.
What is a constraint?
Used to measure how high we drop something from
What is a ruler or a tape measure?
Forces that cancel each other out, there is no change in motion. An object is moving at a constant speed.
What are balanced forces?
How fast something is going
What is speed?
the things that stay the same in an experiment?
What are control variables?
Things that are wanted and that have a range
What is Criteria?
A push or pull
What is a force?
a car is moving at a constant speed, is the forces balanced or unbalanced?
What is balanced forces?
a person pushes an empty box and a box filled with books with the same amount of force, why don't the boxes move the same distance?
What is mass?
the ONE thing that you change in the experiment?
What is an independent variable?
A science project is graded off if it has data, an explanation, and if it has colors, what is the criteria?
What is colors?
The arrows that represent force
What are vectors?
a ball falls out of a tree and it speeds up, are the forces balanced or unbalanced?
What is unbalanced forces?
a car is moving slower and slower as it comes to a stop, what is decreasing?
What is speed?
You change two things in a experiment, is it a fair or unfair experiment?
What is an unfair experiment?
Emma wants a backyard that is big, has a swing set, and trampoline, what are the constraints?
What is a swing set and a trampoline?
Something that protects or slows down contact with an object.
What is cushion?
A car is moving at a constant speed and it takes a right turn, are the forces balanced or unbalanced?
What is unbalanced forces?
A person is stacking more and more books on a table, what is increasing?
What is mass?
Josh is doing an experiment to see which water bottle is stronger. He is dropping a Stanley water bottle and a hydro flask, and he is having the experiment inside and at the same spot, and dropping them from the same height. What is the control variables?
What is the same spot and dropping from the same height?
Jess wants a new pencil case that has 3 compartments, pretty small so easy to carry, and she wants it to be lavender. What is the criteria?
What is pretty small?
Used to measure the mass.
