NEWTON'S LAWS EXAMPLES
Newton's 1st Law: An object will move in a straight line at a constant rate unless acted upon by an external unbalanced force. The skateboard was moving to the right. The rock put a force on the skateboard to make it stop. The glass man riding the skateboard did not stop because no force acted upon him. He continued to move to the right with the same velocity as when he was moving on the skateboard. An object in motion stays in motion.
|
Newton's 1st Law: An object at rest will remain at rest unless acted upon by an external unbalanced force. The tennis balls were initially motionless. Their inertia resists forces that try to make them move. The plate beneath them moves, but the tennis balls remain at rest, and drop into the water cups after the plate is pushed away. They do not move with the plate.
|
Newton's 2nd Law: Acceleration is inversely proportional to the mass of the object. Larger mass resists more, and will accelerate more slowly. Smaller mass resists less, and will accelerate more quickly. The bowling ball has 1000-times the mass of the mass of the balloon. They are kicked with equal force. The balloon moves farther faster. The bowling ball moves slower and not very far.
|
Newton's 2nd Law: Acceleration is inversely proportional to the mass of the object. Larger mass resists more, and will accelerate more slowly. Smaller mass resists less, and will accelerate more quickly. The green figure force to push a larger mass, the larger mass accelerates slowly. The red figure uses force to push a smaller mass, the smaller mass accelerates quickly.

|
Newton's 3rd Law: Forces are paired. When objects interact, the force applied on an object s equal in magnitude and opposite in direction to the force applied by the other on first. The force of the cannon pushing the cannonball to the right is equal to the force of the cannonball pushing the cannon to the left.
Newton's 2nd Law: The forces acting on the cannon and ball are equal in magnitude. The cannonball moves farther faster because it has a smaller mass. The cannon moves a smaller distance slower because it has a larger mass. |
Newton's 3rd Law
Forces are paired. When objects interact, the force applied on an object is equal in magnitude and opposite in direction to the force applied by the other on the first. The force of the gas jets expelled from the fire extinguisher pushes back on the fire extinguisher, making the people move in the opposite direction. |
