Success Criteria:
I am able to describe how force, mass, and acceleration are related according to Newton's Second Law.
I am able to accurately use the formula 𝐹 = 𝑚𝑎 to calculate force, mass, or acceleration when given two of the three variables.
I am able to solve problems involving real-world scenarios where they need to determine the force, mass, or acceleration of objects.
I am able to use correct units for force (Newtons), mass (kilograms), and acceleration (meters per second squared) in calculations and explanations.
Fun Fact
Did you know? Newton’s Second Law can explain why it’s harder to push a car than a bicycle. Both the car and the bicycle obey the same physical laws, but because the car has much more mass than the bicycle, it requires a lot more force to achieve the same acceleration. So next time you're pushing your bike, think of how many more Newtons you'd need to get a car moving at the same speed! 🚲🚗
Key terms
Force is a push or pull on an object that can cause it to accelerate. Measured in Newtons (N).
Mass is the amount of matter in an object, which affects how much force is needed to accelerate it. Measured in kilograms (kg).
Acceleration is the rate at which an object's velocity changes over time. Measured in meters per second squared (m/s²).
Newton's Second Law (F = ma) is the principle that the force acting on an object is equal to its mass times its acceleration.
Net Force is the overall force acting on an object when all individual forces are combined. It determines the object's acceleration.
