What is Newton's 2nd Law of Motion?

Back

Newton's 2nd Law of Motion states that the force acting on an object is equal to the mass of that object multiplied by its acceleration (F = ma).

Front

How do you calculate acceleration?

Back

Acceleration can be calculated using the formula: a = F/m, where F is the force applied and m is the mass of the object.

Front

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

Back

The relationship is defined by Newton's 2nd Law of Motion: Force equals mass times acceleration (F = ma).

Front

What does it mean for two quantities to vary directly?

Back

Two quantities vary directly when an increase in one quantity results in a proportional increase in the other quantity.

What does it mean for two quantities to vary inversely?

Back

Two quantities vary inversely when an increase in one quantity results in a proportional decrease in the other quantity.

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

Back

The height of the object is 8 feet.

What is Ohm's Law?

Back

Ohm's Law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) of the conductor (V = IR).

Front

How do you calculate current using Ohm's Law?

Back

Current can be calculated using the formula: I = V/R, where V is the voltage and R is the resistance.
