What is the law of conservation of mass?

Back

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction. The total mass of the reactants equals the total mass of the products.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to the mass of the object.

Front

Define velocity.

Back

Velocity is a vector quantity that describes the speed of an object in a specific direction.

Front

What factors can increase the strength of an electromagnet?

Back

Adding more coils to the electromagnet and increasing the size of the magnets can enhance the strength of an electromagnet.

Front

What are the three main states of matter?

Back

The three main states of matter are solid, liquid, and gas.

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 includes both speed and direction.

Front

What is an electric motor?

Back

An electric motor is a device that converts electrical energy into mechanical energy through the interaction of magnetic fields.

Front

What is the first law of motion?

Back

The first law of motion, also known as Newton's first law, states that an object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by an external force.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time.

Front

What is a chemical change?

Back

A chemical change is a process that involves the transformation of one or more substances into different substances with distinct properties.
