Final Exam Science 6th

Front

What is net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined. It determines the object's motion.

Front

What happens when two forces of equal magnitude act in opposite directions?

Back

The net force is zero, and the object remains in its current state of motion.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. Objects with greater mass have more inertia.

Front

What is the relationship between mass and inertia?

Back

Objects with greater mass have more inertia, meaning they are harder to start or stop moving.

Front

What are energy transformations?

Back

Energy transformations are changes from one form of energy to another, such as chemical energy to thermal energy.

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like food or fuel.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of particles in an object.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object.

Front

What is a circuit?

Back

A circuit is a closed loop that allows electric current to flow, typically including a power source, wires, and a load.

Front

What happens when a circuit is closed?

Back

When a circuit is closed, electricity flows through the circuit, powering devices like fans or lights.
