Newton's 2nd Law - Stephan A. Green | Biblioteka

1

What does Newton's 2nd Law state about force and mass?

Mass equals force divided by acceleration.

Force equals mass plus acceleration.

Acceleration equals mass divided by force.

Force equals mass times acceleration.

1

Which variable increases when you apply more force?

Weight of the object increases.

Velocity of the object increases.

Mass of the object increases.

Acceleration of the object increases.

1

How is acceleration calculated using Newton's 2nd Law?

Force equals mass plus acceleration.

Acceleration equals force divided by mass.

Force equals acceleration times mass.

Acceleration equals mass divided by force.

What is the formula for Newton's 2nd Law?

F = mv

F = m + a

F = ma

a = F/m

1

If mass increases, what happens to force for constant acceleration?

Force remains constant

Force decreases

Force increases

Force doubles

In Newton's 2nd Law, what causes an object to accelerate?

The object's speed only.

The object's mass only.

An unbalanced force acting on the object.

Balanced forces acting on the object.
