Force
This push or pull causes a change in an object's motion.
What is a force?
The measure of speed with direction included
What is velocity?
The first step of the scientific method.
What is posing a question based on observations and inferences?
Newton's Third Law of Motion.
What is "every action has an equal and opposite reaction?"
The measurement of the difference between the initial and ending position of an object.
What is displacement?
This object exerts the largest gravitational pull on you.
What is the Earth?
A description of and the unit for acceleration.
What is the change in speed over time? What is m/s2?
The variable that you are observing or measuring in an experiment.
What is the dependent variable?
The tendency for any object to resist a change in its motion.
What is inertia?
A measurement that has both magnitude AND direction.
What is a vector?
This force opposes a push or a pull along two surfaces with different textures.
What is force due to friction?
A straight line on a time vs. distance graph demonstrates this sort of speed.
What is constant speed?
The proper format for a hypothesis.
What is "if...then...because"?
The only way to increase an object's inertia.
What is increasing its mass?
The displacement of a chicken that has run 120 km North and then 60 km South.
What is 60 km North?
The net force AND free body diagram for when Aden is pushing a box to the right with a force of 20 N. The carpet exerts a force due to friction of 3 N to the left and the box weighs 100 N.
What is 17 N to the right? (draw the free body diagram)
The speed of Niesha's unicycle if she traveled 150 km in 3 hours.
What is 50 km/h?
The last step of the scientific method.
What is communicating your results?
The force that the wall provides against an elephant when the elephant hits the wall with a force of 1,200N
What is 1,200 N in the opposite direction?
The word used to describe distance, meaning that it measures the total of all the smaller parts of movement.
What is cumulative?
The force of the wind if Samin is riding his bike at 18 m/s and together, he and the bike have a mass of 60kg. The wind comes and slows his bike down to 8 m/s over 5 seconds.
What is 120 N?
Abigail's final speed if she starts walking at 11 m/s and increases her speed 4 m/s2 for 4 seconds.
What is 27 m/s?
Chicken 1: 10 m after 10 seconds, 30 m after 20 s, 40 m after 30 s
Chicken 2: 30 m after 10 s, 60 m after 20 s, 90 m after 30 s
Chicken 3: 20 m after 10, 20 m after 20 s, 50 m after 30 s
What is (your graph)?
When the forces on an object are balanced, this is the net force.
What is 0 N?
Aissatou's distance and displacement after she first travels 30 km/h North for 3 hours and then 45 km South.
What is 135 km? What is 45 km North?
