Precision
How close a measurement is to similar measurements
Accuracy
How close a measurement is to the accepted value
Uncertainty
Significant figures
Random error
An error due to the behaves or of the observer. These typically show up due to difficulties reading instruments. The resulting measurements end up on both sides of the accepted value.
Systematic error
An error due to incorrectly calibrated instruments. The resulting measurements end up being skewed in a single direction from the accepted value.
Front:What is the term for the specific location or arrangement of an object in relation to a reference point?
Back:This term refers to the spatial relationship of an object, often described using coordinates, angles, or distances from a known reference. It is crucial in fields like physics, navigation, and engineering to understand how an object is situated in a given space.
Front: What is a mathematical entity that has both magnitude and direction, often represented as an arrow?
Back:A vector is a quantity that possesses both size (length) and direction in space, used in physics and mathematics to represent forces, velocities, and other directional quantities.
Front:What is the measure of space between two points?
Back:It refers to the amount of space separating two locations, often quantified in units such as meters, kilometers, miles, or feet. It can be calculated using various methods, including the straight line between two points or the total path traveled.
Front:What is the change in position of an object?
Back: It is a vector quantity that refers to the shortest straight-line distance from the initial position to the final position, including the direction of that line.
Front:What is the term that describes the rate of change of velocity of an object over time?
Back:This is a vector quantity that can be positive (increasing speed), negative (deceleration), or zero (constant speed). It is calculated by dividing the change in velocity by the time taken for that change. The standard unit is meters per second squared (m/s²).
Front:What is the formula to calculate the rate of change of distance over time
Back:Speed = Distance / TimeThis equation expresses how fast an object is moving, measured in units like meters per second (m/s) or kilometers per hour (km/h).
What in physics is a quantity that has both magnitude and direction.
A vector in physics is a quantity that has both magnitude and direction. Examples include displacement, velocity, acceleration, and force. Vectors are typically represented graphically by arrows, where the length of the arrow indicates the magnitude and the direction of the arrow indicates the direction of the vector.
Flashcard Front:What is the equation for acceleration?
Flashcard Back:Acceleration is defined as the change in velocity over time. It can be calculated using the formula:a = (v_f - v_i) / twhere:
a = acceleration
v_f = final velocity
v_i = initial velocity
t = time taken for the change in velocity.
Front:What is the formula to calculate the rate of change of an object's position?
Back:Velocity is defined as the displacement of an object divided by the time taken. The equation is:v = Δx / Δtwhere v represents velocity, Δx is the change in position, and Δt is the change in time.
