What is the main difference between distance and displacement?
Distance is the total path length traveled, while displacement is the change in position from initial to final.
How is distance defined in physics?
Distance is the total length of the path traveled by an object and is a scalar quantity.
What type of quantity is distance: scalar or vector?
Distance is a scalar quantity.
What units are used to measure distance?
Meters, kilometers, or miles.
What is displacement in physics?
Displacement is the change in position of an object from its initial position to its final position.
What type of quantity is displacement: scalar or vector?
Displacement is a vector quantity.
How is displacement represented graphically?
Displacement is represented by a vector with an arrow pointing from the initial position to the final position.
What are scalar quantities?
Scalar quantities are physical quantities that have only magnitude and no direction.
Give examples of scalar quantities.
Mass, temperature, time, speed, distance, energy, and power.
How are vector quantities defined?
Vector quantities are physical quantities that have both magnitude and direction.
Give examples of vector quantities.
Displacement, velocity, acceleration, force, and momentum.
How can vector quantities be represented?
Vector quantities are represented graphically as arrows.
What does the length of a vector arrow represent?
The length of the arrow represents the magnitude of the vector.
What does the direction of a vector arrow represent?
The direction of the arrow represents the direction of the vector.
What is the position of an object?
Position is the location of an object relative to a chosen reference point.
What does a Position vs Time Graph indicate?
The slope of a Position vs Time Graph indicates the velocity of the object.
What does a straight line slope on a Position vs Time Graph indicate?
A constant velocity.
What does a curved line slope on a Position vs Time Graph indicate?
There is a change in velocity (acceleration).
What does a zero slope on a Position vs Time Graph indicate?
The object is at rest.
What is speed?
Speed is a scalar quantity that refers to how fast an object is moving.
How is speed calculated?
Speed is calculated by dividing the distance traveled by the time taken.
What is the SI unit of speed?
Meters per second (m/s).
What is velocity?
Velocity is a vector quantity that refers to the rate of change of position.
How is velocity calculated?
Velocity is calculated by dividing displacement by the time taken.
What is the SI unit of velocity?
Meters per second (m/s).
What does a velocity vs time graph depict?
A velocity vs time graph depicts acceleration.
What is acceleration?
Acceleration is the rate of change of velocity with respect to time.
What type of quantity is acceleration?
Acceleration is a vector quantity.
How is acceleration calculated?
a = (v_f - v_i) / t.
What is the SI unit of acceleration?
Meters per second squared (m/s^2).
What does positive acceleration indicate?
An object is speeding up.
What does negative acceleration indicate?
An object is slowing down or moving in the opposite direction of its acceleration.
What is uniform acceleration?
Uniform acceleration is when an object's acceleration is constant over time.
What is non-uniform acceleration?
Non-uniform acceleration is when an object's acceleration changes over time.
What is free fall?
Free fall is a special case of uniform acceleration where an object falls under the influence of gravity.
What is the acceleration due to gravity near the Earth's surface?
Approximately 9.8 m/s^2.
What is the formula for the distance fallen in free fall?
d = (1/2)gt^2.
What is uniformly accelerated motion?
Motion where the acceleration of an object remains constant.
What are the BIG FIVE equations of motion?
Equations that describe motion under uniformly accelerated conditions.
What is the equation v = u + at used for?
To find final velocity given initial velocity, acceleration, and time.
What does s = ut + 1/2at^2 calculate?
Displacement during uniformly accelerated motion.
What does v^2 = u^2 + 2as describe?
The relationship between initial velocity, final velocity, acceleration, and displacement.
What is the maximum height formula in projectile motion?
h = (v₀sinθ)² / 2g.
What is the range of a projectile?
R = v₀²sin2θ / g.
What does projectile motion describe?
The motion of an object thrown or launched into the air under gravity.
What path does a projectile follow?
A parabolic curve.
What makes the horizontal component of motion in projectile motion constant?
It experiences no horizontal acceleration.
What is the dependency between horizontal and vertical motion in angled motion?
They are interdependent.
What formula gives the time of flight for an angled projectile?
t = 2v₀sinθ / g.
What does the horizontal component of velocity equal in angled motion?
v₀cosθ.
What does the vertical component of velocity equal in angled motion?
v₀sinθ - gt.
