8.6A F=MxA Flashcard #1

Front

What is Newton's Second Law of Motion?

Back

Newton's Second Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. It can be expressed with the formula F = m × a.

Front

What does the symbol 'F' represent in the equation F = m × a?

Back

'F' represents the force applied to an object, measured in Newtons (N).

Front

What does the symbol 'm' represent in the equation F = m × a?

Back

'm' represents the mass of the object, measured in kilograms (kg).

Front

What does the symbol 'a' represent in the equation F = m × a?

Back

'a' represents the acceleration of the object, measured in meters per second squared (m/s²).

Front

How do you calculate force if you know mass and acceleration?

Back

Force can be calculated using the formula F = m × a, where you multiply the mass (m) of the object by its acceleration (a).

Front

If a 20-kg bowling ball is accelerated at 5 m/s², what force is needed?

Back

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

Front

What is the acceleration of a 100-kg shopping cart pushed with a force of 300 N?

Back

3 m/s² (calculated using a = F/m: a = 300 N / 100 kg).

Front

How do you find the mass of an object if you know the force applied and its acceleration?

Back

Mass can be found using the formula m = F/a, where you divide the force (F) by the acceleration (a).

Front

If an evil ewok throws a rock with a force of 24.6 N and an acceleration of 6 m/s², what is the mass of the rock?

Back

4.1 kg (calculated using m = F/a: m = 24.6 N / 6 m/s²).

Front

Which object requires the greatest force to move if all have the same acceleration?

Back

The object with the greatest mass requires the greatest force, as force is the product of mass and acceleration.
