Key terms
acceleration
The rate of change of velocity of an object, measured in metres per second squared (m/s²).
uniform acceleration
A constant acceleration where the velocity of an object changes at a steady rate over time.
Uniform acceleration
Acceleration that occurs at a constant rate, where the change in velocity is consistent over time.
Distance calculation
The process of determining the distance travelled using the equation v^2 - u^2 = 2as, where v is final velocity, u is initial velocity, a is acceleration, and s is distance.
Uniform acceleration
A constant acceleration that occurs when the rate of change of velocity is the same over time.
Acceleration
The rate of change of velocity of an object, measured in metres per second squared (m/s²).
Uniform acceleration
A constant acceleration experienced by an object moving in a straight line.
Square root
A mathematical operation that finds a number which, when multiplied by itself, gives the original number.
consistent units
Units that are uniform and compatible for measurements of velocity, acceleration, and distance.
uniform acceleration
Acceleration that remains constant over time, resulting in a steady increase in velocity.
Uniform acceleration
Acceleration that occurs at a constant rate, where the change in velocity is uniform over time.
Rearranging equations
The process of manipulating an equation to isolate a specific variable, often used in physics calculations.
Newton's first law
An object will remain at rest or in uniform motion in a straight line unless acted upon by a resultant force.
resultant force
The overall force acting on an object when all individual forces acting on it are combined.
Resultant Force
The overall force acting on an object when all individual forces are combined.
Equilibrium
A state where the resultant force on an object is zero, resulting in no change in motion.
resultant force
The overall force acting on an object when all individual forces are combined.
constant velocity
The state of an object moving at a uniform speed in a straight line without changing direction.
resultant force
The overall force acting on an object when all individual forces are combined.
acceleration
The rate of change of velocity of an object, measured in metres per second squared (m/s²).
Newton's second law
The principle stating that the resultant force acting on an object is equal to the mass of the object multiplied by its acceleration.
resultant force
The overall force acting on an object when all individual forces acting on it are combined.
resultant force
The overall force acting on an object, calculated as the vector sum of all individual forces.
acceleration
The rate of change of velocity of an object, measured in metres per second squared (m/s²).
resultant force
The overall force acting on an object, calculated by vector addition of all individual forces.
acceleration
The rate of change of velocity of an object, measured in metres per second squared (m/s²).
resultant force

inertial mass
A measure of how difficult it is to change an object's velocity.
resultant force
The overall force acting on an object, calculated by vector addition of all individual forces.
