Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion, calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

What factors affect the strength of an electric motor?

Back

The strength of an electric motor can be affected by the number of coils of wire, the strength of the magnetic field, and the voltage of the power source.

Front

What are the three main types of heat transfer?

Back

The three main types of heat transfer are conduction (direct contact), convection (movement of fluids), and radiation (transfer through electromagnetic waves).

Front

How does conduction work?

Back

Conduction is the transfer of heat through direct contact between materials, where faster-moving particles collide with slower-moving ones, transferring energy.

Front

What is the role of convection in heat transfer?

Back

Convection involves the movement of fluids (liquids or gases) where warmer, less dense areas rise and cooler, denser areas sink, creating a circulation pattern.

Front

What is radiation in terms of heat transfer?

Back

Radiation is the transfer of heat through electromagnetic waves, which can occur in a vacuum, such as heat from the Sun reaching the Earth.

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction, defined as the change in position over time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What happens to the motion of an object when it experiences a net force?

Back

When an object experiences a net force, it will accelerate in the direction of the net force according to Newton's second law of motion (F=ma).

Front

What is charge distribution?

Back

Charge distribution refers to how electric charge is spread out in a material or system, which can affect the behavior of nearby charged objects.
