Newton's Second Law

Front

What is Newton's Second Law of Motion?

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 = ma.

Front

What does the symbol 'F' represent in the equation F = ma?

Back

'F' represents the net force acting on an object, measured in Newtons (N).

Front

What does the symbol 'm' represent in the equation F = ma?

Back

'm' represents the mass of the object, measured in kilograms (kg).

Front

What does the symbol 'a' represent in the equation F = ma?

Back

'a' represents the acceleration of the object, measured in meters per second squared (m/s²).

If a 10 kg object is slowing down at a rate of -3 m/s², what is the force on the object?

Back

-30 N

Front

What is the acceleration of a 20 kg object if it is being pushed with a force of 100 N?

Back

5 m/s²

Front

What is the force on a 500 kg object that's accelerating at 3 m/s²?

Back

1500 N

Front

A 10 kg bowling ball would require what net force to accelerate down an alleyway at a rate of 3 m/s²?

Back

30 N

Front

What is the mass of a truck if it produces a force of 14,000 N while accelerating at 5 m/s²?

Back

2800 kg

Front

How do you calculate net force?

Back

Net force is calculated using the formula: F = ma, where 'F' is the net force, 'm' is the mass, and 'a' is the acceleration.
