Newton's Laws

Front

What is Newton's First Law known as?

Back

The Law of Inertia

Front

What is inertia?

Back

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

Front

What is the formula to calculate force?

Back

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

Front

If a 10 kg object accelerates at 15 m/s², what is the force applied?

Back

150 Newtons

Front

What kind of objects have inertia?

Back

All objects with mass.

Front

What is Newton's Second Law?

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 unit of force?

Back

Newton (N)

Front

What is an example of action and reaction forces?

Back

When a bat hits a ball, the action is the bat hitting the ball, and the reaction is the ball pushing back against the bat.

Front

How much force is needed to accelerate a 3 kg skateboard at 5 m/s²?

Back

15 Newtons

Front

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

Back

As mass increases, acceleration decreases for a given force.
