Front

What is the formula for calculating velocity?

Back

Velocity = Distance / Time

Front

What is linear regression?

Back

Linear regression is a statistical method used to model the relationship between a dependent variable and one or more independent variables by fitting a linear equation to observed data.

Front

What does Newton's 2nd Law of Motion state?

Back

Newton's 2nd Law states that Force (F) equals mass (m) times acceleration (a), or F = ma.

Front

How do you calculate acceleration?

Back

Acceleration = Force / Mass

Front

What is the relationship between mass, force, and acceleration?

Back

The relationship is defined by Newton's 2nd Law: F = ma.

Front

If a ball is dropped, what is its initial velocity?

Back

The initial velocity of a dropped ball is 0 ft/sec.

Front

What is direct variation?

Back

Direct variation is a relationship between two variables where one variable is a constant multiple of the other.

Front

If the shadow of an object is 27 feet when the height is 12 feet, what is the height when the shadow is 18 feet?

Back

The height is 8 feet.

Front

What is the mass of an object if it produces a force of 14,000 Newtons while accelerating at 5 m/s²?

Back

The mass is 2800 kg.

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force is the Newton (N).
