8.6A F=MxA Flashcard #4

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 is the formula to calculate force?

Back

The formula to calculate force is F = m × a, where F is force in Newtons, m is mass in kilograms, and a is acceleration in meters per second squared.

Front

How do you calculate acceleration?

Back

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

Front

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

Back

The unit of force in the SI system is the Newton (N).

Front

If a 2000 kg object is pushed with a force of 800 N, what is its acceleration?

Back

0.4 m/s².

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

What is the acceleration of a 25 kg skateboard when a force of 75 N is applied?

Back

3 m/s².

Front

What is the force acting on a 500 kg elevator falling freely at 7 m/s²?

Back

3,500 N.

Front

What is the acceleration of a vehicle with a mass of 1,000 kg and a net force of 2,500 N acting on it?

Back

2.5 m/s².

Front

What is the greatest acceleration among a Sedan, Coupe, SUV, and Truck if the Coupe has the least mass and highest force applied?

Back

Coupe.
