WYA?
What the Formula!
100
This scalar quantity refers to the distance an object travels over a period of time?
What is Speed?
100
This type of force is the contact force exerted by the surface of an object that is perpendicular to and pointed away from the surface.
What is FN / Normal Force?
100
This is a push or pull.
What is force?
100
The part of a position vs time graph that always represents time.
What is the x-axis?
100
This is the formula for speed.
What is distance over time (s = d/t , d = distance)?
200
Speed with direction.
What is velocity?
200
This is the force exerted by a string or rope when attached to a body.
What is FT / Tension?
200
Newton’s 2nd law relates these 3 variables.
What is force, mass, and acceleration?
200
This vertical line on the position vs time graph represents an object
What is at rest?
200
This is displacement over time (? = d/t , d = displacement).
What is velocity?
300
This is the objects average speed during the first 4s
What is 8m/4s = 2m/s?
300
The 4 steps to drawing a free body diagram are:
What is pick an object to analyze, draw a box to represent the object, draw an arrow to represent each force acting on the object, and make sure the arrow shows the direction and relative size of the force?
300
This states that an object acted upon by an unbalanced force will accelerate in the direction of the force.
What is Newton's 2nd Law of Motion?
300
An object moving with a constant velocity has this type of graph shape.
What is a straight line?
300
This is Newton’s 2nd law.
What is F=m*a?
400
The average velocity of a car that travels 30 kilometers due west in 0.50 hrs.
What is 60 km/hr West?
400
A man drags a sled across loosely packed snow with a rightward acceleration. This is the free body diagram of the forces acting on the sled.
400
This is the magnitude of the resultant force of a 6kg object undergoing an acceleration of 2m/s2.
What is 12N?
400
This formula gives us the velocity of an object using the line on the position vs time graph.
What is (y2-y1) / (x2-x1)?
400
This is how to calculate acceleration, when given force and mass.
What is a=F/m?
500
A girl rides her bicycle 1.40 kilometers west, 0.70 kilometers south, and 0.30 kilometers east in 12 minutes.
A) This is the girl’s distance traveled for the entire bicycle trip, in kilometers.
B) This is the girl’s displacement traveled for the entire trip, in kilometers.
What is 1.40 + 0.70 + 0.30 = 2.4 kilometers? (Distance)
What is = 1.3 km NE? (Displacement)
500
This is a free body diagram for a gymnast holding onto a bar, suspended motionless in mid-air. The bar is supported by two ropes that attach to the ceiling.
500
This is the acceleration of a wagon that has a mass of 30 kg and a net force of 180N.
What is 6 m/s2?
500
This type of motion is described as _________
What is positive acceleration, accelerated motion, or increasing positive velocity?
500
This is how to calculate acceleration when given velocity and time.
What is final velocity minus initial velocity divided by time (a = (vf - vi) / time)?
