chp 6 newton's 2nd law flashcardizz review

Front

What is the SI unit of measurement for force?

Back

Newtons

Front

What type of force causes acceleration?

Back

Unbalanced force

Front

Calculate the force applied to an object with a mass of 2.0 kg that accelerates at 2.0 m/s² using F = m x a.

Back

4.0 Newtons

Front

What is true about freely falling objects?

Back

They all fall with the same acceleration, the net force acting on them is their weight, their weight-to-mass ratio is always the same, and their acceleration is g, the acceleration due to gravity.

Front

Is acceleration directly proportional to the net force?

Back

True

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

If a net force of 10 N is applied to a 2 kg object, what is its acceleration?

Back

5 m/s²

Front

What happens to the acceleration of an object if the mass is doubled while keeping the force constant?

Back

The acceleration is halved.

Front

What is the formula to calculate force?

Back

F = m x a

Front

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

Back

As mass increases, acceleration decreases.
