Kinematics
These quantities are defined as having only magnitude, not direction.
What are scalars?
This is the specific term for an object’s resistance to a change in its motion.
What is inertia?
This is defined as the ability to do work.
What is energy?
This mathematical formula is used to calculate momentum.
What is p=mv?
This is the formula used to calculate mechanical work.
What is W=Fd?
This vector quantity indicates a change in position.
What is displacement?
These types of forces, such as gravity or magnetism, act between objects that are not touching.
What are field forces?
This main type of energy is often called the "energy of position."
What is potential energy?
This type of collision occurs when objects collide and rebound, conserving both momentum and kinetic energy.
What is elastic collision?
This term describes the rate of doing work, measured in Watts.
What is power?
This is the mathematical formula for calculating speed or velocity.
What is v = d/Δt?
This is the state of a system when all simultaneous forces cancel each other out, resulting in no net force.
What is mechanical equilibrium?
This form of energy is described as the average sum of the kinetic energy of all particles in an object.
What is thermal energy?
In this type of collision, objects collide and then stick together.
What is inelastic collision?
In this class of lever, the resistance (load) is located between the fulcrum and the effort.
What is a second-class lever?
This is the rate of change of speed or velocity during a given time interval.
What is acceleration?
This formula is used to calculate the weight of an object on Earth.
What is Fg=mg?
This type of potential energy is stored in the bonds of molecules and atoms.
What is chemical energy?
This law states that within a system, the total quality of motion remains constant unless acted on by external forces.
What is the Law of Conservation of Momentum?
This is produced when a force acts perpendicular on a lever rotating around a pivot point.
What is torque (τ)?
This is the specific type of reference frame used when the observation point is accelerating.
What is an accelerated reference frame?
This condition occurs when gravity is the only force acting on a falling object.
What is free fall?
This term describes the energy associated with the nucleus of an atom, released through fission or fusion.
What is nuclear energy?
Most real-world collisions fall into this category, where objects rebound and are deformed.
What is a partially elastic collision?
This is the Ideal Mechanical Advantage (IMA) of a single movable pulley.
