Newton’s 2nd Law
What is the formula for Newton's 2nd Law of Motion?
What is F=ma?
What does Newton's 3rd Law of Motion state?
For every action, there is an equal and opposite reaction.
If a car has a mass of 1,000 kg and accelerates at a rate of 3 m/s², what is the net force acting on it?
What is 3,000 N?
Give an example of Newton's 3rd Law in everyday life and explain how it demonstrated Newton's 3rd Law.

How does increasing the mass of an object affect its acceleration if the force applied remains constant?
It decreases the acceleration.
If a swimmer pushes against the water, what happens to the swimmer?
The swimmer moves forward due to the reaction force of the water pushing back.
In what units is force measured in?
Newtons (N)
How does Newton's 3rd Law explain the movement of rockets?
Rockets push down on the ground with their engines, and the ground pushes the rocket upward.
If a soccer ball has a mass of 0.5 kg and is kicked, resulting in an acceleration of 10 m/s², what is the force exerted on the ball?
What is 5N?
In what scenario would you observe Newton's 3rd Law in action when playing basketball?
When a player dribbles the ball, the ball exerts a force on the ground, and the ground exerts an equal force back on the ball, causing it to bounce.
