8.6A F=MxA Flashcard #2

Front

What is Newton's Second Law of Motion?

Back

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

Front

How do you calculate force?

Back

Force is calculated using the formula F = m × a, where F is force in newtons, m is mass in kilograms, and a is acceleration in meters per second squared.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

If a 2 kg object accelerates at 3 m/s², what is the force applied?

Back

6 N (calculated using F = m × a: F = 2 kg × 3 m/s²).

Front

What is the mass of an object if a force of 20 N is applied and it accelerates at 4 m/s²?

Back

5 kg (calculated using m = F/a: m = 20 N / 4 m/s²).

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, measured in meters per second squared (m/s²).

Front

How do you calculate acceleration?

Back

Acceleration is calculated using the formula a = F/m, where a is acceleration, F is force, and m is mass.

Front

What is the relationship between mass and acceleration when force is constant?

Back

When force is constant, an increase in mass results in a decrease in acceleration, and vice versa.

Front

If a force of 100 N is applied to a 25 kg object, what is its acceleration?

Back

4 m/s² (calculated using a = F/m: a = 100 N / 25 kg).

Front

What is the effect of increasing force on acceleration?

Back

Increasing force results in an increase in acceleration, assuming mass remains constant.
