Newton's Second Law of Motion

Front

What is Newton's Second Law of Motion?

Back

Newton's Second Law states that the force acting on an object is equal to the mass of that object multiplied by its acceleration (F = ma).

Front

How do you calculate force using mass and acceleration?

Back

Force (F) is calculated using the formula F = ma, where m is mass and a is acceleration.

Front

If an object has a mass of 2,100 kg and accelerates at 7 m/s², what is the force acting on it?

Back

The force is 14,700 N (F = 2100 kg * 7 m/s²).

Front

What happens to the velocity of an object when a force is applied in the same direction as its motion?

Back

The object's velocity increases, meaning it will go faster.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity over time.

Front

True or False: An object's velocity can be changed by changing its speed, its direction, or both.

Back

True.

Front

If a force of 26 N is applied to two objects of different masses, how do you determine which object has greater acceleration?

Back

Use F = ma; the object with the smaller mass will have greater acceleration.

Front

What is the relationship between mass and acceleration when a constant force is applied?

Back

As mass increases, acceleration decreases if the force remains constant.

Front

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

Back

The unit of force is the Newton (N).

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.
