Newton's Basics
Newton's 1st Law
Newton's 2nd Law
Newton's 3rd Law
100
The force(s) acting on any free falling object
What is force of gravity (could say air resistance, too, but we typically ignore this)
100
Newton's first law
What is an object at rest will remain at rest and an object in motion will maintain its motion at a constant velocity unless acted upon by a net external force.
100
Newton's second law
What is the sum of the external forces on an object is directly proportional to the product of its mass and acceleration...AKA Fnet=ma
100
Newton's third law
What is that whenever one object exerts a force on a second object, the second object exerts an equal force on the first object in the opposite direction.
There is no such thing as a lone force; all forces come in pairs.
200
The cause of any acceleration (or deceleration).
What is force.
200
The net force of the following object, based on the free-body diagram:
What is 0 N
200
The net force of an 10 kg object accelerating at a rate of 10 m/s2.
What is 100 N
200
The pair of forces in the following scenario: A kickboxer punches a punching bag.
What is the kickboxer punches the bag and the bag "punches" the kickboxer.
300
The term describes an objects tendency to resist changes in motion.
What is inertia
300
The free body diagram for a book at rest on a table.
What is
300
An object is accelerating at a rate of 5 m/s2 when it suddenly has the net force exerted upon it increased by a factor of 2. The new acceleration will be...
What is 10 m/s2
300
Boulder A (125.25 kg) hits boulder B (125.25 kg) with a force of 1050 N. Compare and contrast the acceleration experienced by the two boulders.
What is both boulders experience the same magnitude of acceleration (at 8.38 m/s2), but they move in opposite directions of each other.
400
The type of force that opposes motion.
What is friction
400
The free body diagram for a car that is accelerating to the right.
What is
400
The net force of an 800 kg car that accelerates from 0 m/s to 50 m/s in 8.9 seconds. (Ignoring friction)
What is 4494.38 N.
400
An 100 kg hammer hits a 0.1 kg nail into the wall with a force of +100 N.
a. What is the force (and direction) of the nail on the hammer?
b. What is the acceleration experienced by the nail?
What is
a. -100 N
b. 1000 m/s2
500
The definition of weight
What is the measurement of how hard the force of gravity is being exerted on an object.
500
The missing force values for the following diagram:
What is
D = 20 N
E = 300 N
500
The force required to lift a 10 kg box into the air in 3 seconds at a rate of 1 m/s.
What is 101.43 N
500
While playing hockey at the ice rink, Bart (at 100 kg) pushes another stationary player with a mass of 102 kg to the right. If the player experiences an acceleration of 1.127 m/s2 to the right, what acceleration does Bart experience?
What is 1.15 m/s2 (to the left)
