Newton's 2nd Law of Motion

Front

What are the SI units for force?

Back

Newtons

Front

If all objects are struck with the same amount of force, which object will have the greatest acceleration?

Back

The object with the least mass will have the greatest acceleration.

Front

What does 45 m/s² represent?

Back

Acceleration

Front

Why does a crumpled piece of paper hit the ground before a flat sheet of paper?

Back

There is more air resistance against the flat paper.

Front

What is the net force on a box pushed with 10N to the right and 8N to the left?

Back

2N to the right.

Front

State Newton's 2nd 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 for calculating force?

Back

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

Front

If an object has a mass of 5 kg and an acceleration of 3 m/s², what is the force applied?

Back

15 N (Force = 5 kg × 3 m/s²).

Front

What happens to acceleration if mass increases while force remains constant?

Back

Acceleration decreases.

Front

What is the relationship between mass and acceleration in Newton's 2nd Law?

Back

As mass increases, acceleration decreases for a constant force.
