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 reactants equals the total mass of products.

Front

What does Newton's 1st Law state?

Back

Newton's 1st Law, also known as the Law of Inertia, states that an object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity unless acted upon by a net external force.

Front

What is Newton's 2nd Law of Motion?

Back

Newton's 2nd Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. It can be expressed as F=ma (Force = mass x acceleration).

Front

What is Newton's 3rd Law of Motion?

Back

Newton's 3rd Law states that for every action, there is an equal and opposite reaction.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration. For example, a rock at the top of a hill has gravitational potential energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

Front

What is friction?

Back

Friction is the force that opposes the motion of an object. It occurs when two surfaces come into contact.

Front

What is work in physics?

Back

Work is done when a force is applied to an object and the object moves in the direction of the force. It is calculated as Work = Force x Distance.

Front

What is displacement?

Back

Displacement is the shortest distance from the initial to the final position of an object, along with the direction.

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s).
