Newton's Second Law

Front

What is Newton's Second Law?

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 = mass * acceleration.

Front

What happens when unbalanced forces act on an object at rest?

Back

The object begins moving in the direction of the net force.

Front

What is the formula to calculate force?

Back

F = mass * acceleration.

Front

If a 20 kg bike accelerates at 10 m/s², what is the force acting upon it?

Back

200 Newtons.

Front

What unit do we measure force in?

Back

Newtons.

Front

According to Newton's Second Law, how is acceleration calculated?

Back

Acceleration is calculated by dividing the net force acting on an object by the object's mass.

Front

If an object with a mass of 6.0 kg accelerates at 4.0 m/s², what is the force applied?

Back

24 N.

Front

What is the relationship between mass, acceleration, and force?

Back

The relationship is defined by Newton's Second Law: F = mass * acceleration.

Front

What does it mean for forces to be unbalanced?

Back

Unbalanced forces result in a change in the motion of an object, causing it to accelerate.

Front

What is the net force?

Back

The net force is the total force acting on an object after all the individual forces are combined.
