Newtons Second Law

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

What two variables define force?

Back

Mass and acceleration.

Front

How do you calculate force?

Back

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

Front

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

Back

150 Newtons.

Front

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

Back

Acceleration decreases.

Front

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

Back

Acceleration increases.

Front

If I apply the same force to a ping pong ball and a bowling ball, which one will accelerate faster?

Back

The ping pong ball.

Front

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

Back

Newton (N).

Front

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

Back

The greater the mass of an object, the more force is required to accelerate it.

Front

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

Back

15 Newtons.
