Front

What is constant speed?

Back

Constant speed means that an object covers equal distances in equal intervals of time, regardless of how small those intervals are.

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 an object in motion when no unbalanced forces act on it?

Back

It will continue moving at the same velocity.

Front

How do you calculate distance traveled when speed and time are known?

Back

Distance = Speed x Time.

Front

What is acceleration?

Back

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

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

What is a chemical equation?

Back

A chemical equation is a symbolic representation of a chemical reaction, showing the reactants and products.

Front

What does it mean to have 4 different elements in a chemical equation?

Back

It means that there are four distinct types of atoms present in the reactants and products of the reaction.

Front

What is the significance of direction in velocity?

Back

Direction is crucial in velocity because it determines the object's path and can affect the outcome of motion.

Front

What is the relationship between speed, distance, and time?

Back

Speed is directly proportional to distance and inversely proportional to time.
