What is Hooke's Law?

Back

Hooke's Law states that the amount a spring is stretched (s) varies directly with the force (F) applied to it, expressed as F = k * s, where k is the spring constant.

Front

If a spring stretches 2.3 inches with 80 pounds, how far will it stretch with 100 pounds?

Back

2.875 inches.

Front

What is Ohm's Law?

Back

Ohm's Law states that the voltage (V) across a conductor is directly proportional to the current (I) flowing through it and the resistance (R) of the conductor, expressed as V = I * R.

Front

Calculate the voltage of a circuit with 0.2 amperes and 4800 ohms resistance.

Back

960 volts.

Front

How do you calculate resistance using Ohm's Law?

Back

Resistance (R) can be calculated using the formula R = V / I, where V is voltage and I is current.

Front

What is the formula for Newton's Second Law of Motion?

Back

Newton's Second Law states that the force (F) acting on an object is equal to the mass (m) of the object multiplied by its acceleration (a), expressed as F = m * a.

Front

Calculate the acceleration of a 0.5 kg softball hit with a force of 25 N.

Back

50 m/s².

Front

What is Boyle's Law?

Back

Boyle's Law states that the pressure (P) of a gas is inversely proportional to its volume (V) when temperature is held constant, expressed as PₐVₐ = PᵦVᵦ.

Front

If a gas at 1.10 atm has a volume of 326 cm³, what will be the volume at 1.90 atm?

Back

188.74 cm³.

Front

What is the relationship between pressure and volume in Boyle's Law?

Back

As pressure increases, volume decreases, and vice versa, when temperature is constant.
