What is Newton's Second Law of Motion?

Back

Front

Back

The symbol 'm' represents mass, which is the amount of matter in an object.

Front

What is the relationship between net force and acceleration?

Back

Net force is directly proportional to acceleration. This means that as the net force increases, the acceleration of the object also increases, assuming mass remains constant.

Front

If a car has a mass of 1000 kg and accelerates at 2 m/s², what is the net force acting on it?

Back

Front

What is the formula to calculate acceleration?

Back

Front

If a force of 20 N is applied to a 4 kg object, what is the resulting acceleration?

Back

Front

What does it mean for two quantities to be directly proportional?

Back

Two quantities are directly proportional if an increase in one quantity results in a proportional increase in the other quantity.

Front

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

Back

The unit of force in the SI system is the Newton (N).

Front

How do you calculate net force when multiple forces are acting on an object?

Back

Net force is calculated by vectorially adding all the individual forces acting on the object, taking into account their directions.

Front

What is inertia?

Back

Inertia is the property of an object to resist changes in its state of motion. It is directly related to the mass of the object.
