Intro to Physics
This is the "most basic science" because it's the foundation for all other sciences.
What is Physics?
The term to describe an object's change in position
What is Displacement?
The accepted value of acceleration due to gravity, including units
What is 9.8 m/s2?
The term for an object's tendency to resist changes to its state of motion
What is Inertia?
The momentum of a stationary object
What is 0 kg m/s (no momentum)?
This is term for the ongoing process to test a hypothesis and draw conclusions
What is the Scientific Method?
Velocity is the same as speed but with _____
What is Direction?
The term for an object falling under the influence of only gravity
What is Freefall?
The force that local gravity applies to a mass
What is Weight?
A collision that generates heat and distorts objects permanently
What is an inelastic collision?
A statement about what will happen under certain conditions (Hint: hypothesis, law, or theory)
What is a Law?
When an object speeds up, slows down, or changes direction
What is Acceleration?
The term for any measurement that requires both magnitude and direction
What is a Vector?
Action: hand pushes wall with 200 N
Reaction ?
What is Wall pushes Hand with 200 N?
The units for impulse
What is N s (newton-seconds)?
The variable that the experimenter changes in the experiment
What is an Independent Variable?
The variable on the x-axis of a position vs time graph
What is Time?
The horizontal (x direction) acceleration of a projectile
What is 0 m/s2 (no acceleration)?
Law: "Acceleration is directly proportional to net force"
What is Newton's 2nd Law?
Law: "Net momentum of a system is unchanging in the absence of force"
What is the Law of Conservation of Momentum?
97 centimeters converted to meters (100 cm = 1 m)
What is 0.97 m?
The velocity of an object that travels 24 meters in 6 seconds. (v = x/t)
What is 4 m/s?
The resultant velocity (hypotenuse) of 3 m/s North and 4 m/s East (a2 + b2 = c2)
What is 5 m/s Northeast?
The acceleration of an 8 kg object acted on by 40 N of net force. (a = Fnet/m)
What is 5 m/s2?
The momentum of a 9 kg object that travels at 3 m/s. (p = mv)
What is 27 kg m/s?
