100
What is a reference point?
What is a starting point used to describe the position of an object.
100
How do you calculate average speed?
What is total distance, divided by total time.
100
What is a force, contact force, and a non-contact force?
What is a push or pull, a force that is exerted only when two objects are touching, and a force that one object exerts on another when they are not touching.
100
What is Newton's First law of motion?
What is an object at rest stays at rest until a force with greater inertia acts upon it, and visa versa.
100
What is elastic force, tension force, compression force, and normal force?
What is the force exerted by a material when it is stretched or compressed, a pulling force applied to an object that can make the object stretch, a squeezing force applied to an object that can make an object shrink, and a force exerted by an object that is perpendicular to the surface of the object.
200
What is velocity?
What is a vector that represents an object's speed and direction.
200
What is acceleration?
What is the rate at which velocity changes with time.
200
True or False: Is Force a vector?
What is True.
200
What is gravity?
What is an attractive force that exists between all objects that have mass.
200
What is centripetal force?
What is the force that is perpendicular to the velocity and toward the center of the circle.
300
What is a vector?
What is a quantity with both size and direction.
300
How do you calculate slope?
What is rise over run.
300
What is net force?
What is the combination of all the forces acting on an object.
300
What is the law of universal gravitation?
What is all objects are attracted to each other with a force that depends on the masses of the objects, and the distance between them.
300
What is Newton's second law of motion?
What is acceleration equals the net force divided by mass. (A=Fnet/M)
400
What is speed?
What is the rate of change of position with time.
400
If a train travels at the rate of 40 ft/min. What distance will it travel in 4 minutes.
What is 160 feet.
400
What is unbalanced, and balanced forces?
What is when the net force is not zero, and when the net force is zero.
400
What is weight?
What is the gravitational force exerted on the object.
400
What is Newton's third law of motion?
What is when one object exerts a fore on a second object, the second object exerts an equal force in the opposite direction on the first object.
500
What is the difference between average speed and instantaneous speed?
What is average speed is a speed recorded over an amount of time, and instantaneous speed is a speed at one moment in time.
500
What is displacement? What is the difference between displacement and distance?
What is the difference between the initial position and final position. The difference would be if I walked in a complete circle and stopped where I started exactly. My displacement is zero, and my distance is 10 feet.
500
Calculate: If twins are pushing a cabinet, and one pushes with a force of 200 N, and the other one is pushing from the other side at a force of 100 N, what is the net force?
What is 100 Newtons.
500
What is friction?
What is a force that opposes the movement between two surfaces in contact.
500
A tow truck exerts a force of 6000 Newtons on a car accelerating it at 8 meter per second squared. What is the mass of the car?
What is 750 grams.
