Ap Physics 1 Exam Questions & DetailedAnswers 2024
Displacement (Δx) - ANS -Net change in position
-Measured in meters (m)
Δx = x(f) - x(i)
Velocity (v) - ANS -Speed and direction
-Measured in meters per second (m/s)
average v = Δx/t
Acceleration (a) - ANS -Rate of change of velocity w/ respect to time
-Measured in meters per second squared (m/s^2)
average a = Δv/t
Speeding up vs. Slowing Down - ANS -Speeding up occurs when velocity and
acceleration have the same sign
-Slowing down occurs when velocity and acceleration have opposite signs
Position vs. Time Graph - ANS -Slope represents average velocity
-Object changes direction when graph crosses x-axis
Velocity vs. Time Graph - ANS -Slope represents average acceleration
-Area represents displacement
Acceleration vs. Time Graph - ANS -Area represents change in velocity
Scalars - ANS Quantities with only a size/magnitude (ex: speed, mass, length,
temperature, time, distance, energy, etc.)
, Vectors - ANS Quantities with both a size and direction (ex: displacement,
velocity, position, acceleration, force, etc.)
Projectile Motion - ANS -Horizontal and vertical components are
independent of each other
-Complementary angles travel same horizontal distance
-Larger angles travel higher and spend more time in air, while smaller angles
have greater horizontal velocities
Force (F) - ANS -A push or pull
-Measured in Newtons (N)
Newton's 1st Law - ANS An object will move at a constant velocity in a
frictionless, airless vacuum unless another force is exerted on it
Inertia - ANS -property of an object that resists a change in motion
-measured in mass
Newton's 2nd Law - ANS Net force = mass x acceleration
Newton's 3rd Law - ANS Every action has an equal and opposite reaction
Normal Force (Fn) - ANS A contact force between force between two hard
surfaces
Weight - ANS -Force of gravity on an object
-Depends on mass of object and strength of gravitational field
-Measured in Newtons (N)
Mass - ANS -How much stuff an object is made of
-Mass is independent of location of object
-Measured in kilograms (kg)
