FMA Triangle 1

Front

What is the force on a 1000 kg elevator that is falling freely at 9.8 m/sec²?

Back

9,800 N

Front

What is a force?

Back

A force is a push or pull. It can be balanced or unbalanced.

Front

What is the acceleration of a 50 kg object pushed with a force of 500 newtons?

Back

10 m/s²

Front

A 50 kg skater pushed by a friend accelerates at 5 m/sec². How much force did the friend apply?

Back

250 N

Front

What is the mass of an object that is accelerating at 60 m/s² when a force of 3000 N is exerted?

Back

50 kg

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

What is the formula to calculate force?

Back

Force = Mass × Acceleration (F = m × a)

Front

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

Back

Newton (N)

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change the motion of an object, while unbalanced forces cause an object to accelerate.

Front

If a 10 kg object is at rest, what is the net force acting on it?

Back

0 N (since it is at rest and forces are balanced).
