Newton's Laws of Motion
- First Law of Motion
- States that an object at rest will remain at rest, and an object moving at a constant velocity will continue moving at a constant velocity, unless acted upon by an unbalanced force
- Inertia
- Tendency of an object to resist a change in motion
- Tendency of an object to resist a change in motion
- Inertia Depends on Mass
- Some objects have more inertia than other objects
- The greater the mass of an object, the greater the inertia, greater the force is required to change its motion
- Some objects have more inertia than other objects
- States that an object at rest will remain at rest, and an object moving at a constant velocity will continue moving at a constant velocity, unless acted upon by an unbalanced force
- Second Law of Motion
- Determining Acceleration
- According to Newton's second law of motion, acceleration depends on the object's mass and on the
net force acting on the object
- Acceleration: Net Force/Mass
- According to Newton's second law of motion, acceleration depends on the object's mass and on the
net force acting on the object
- Changes in Force and Mass
- A way to increase acceleration is to change the mass
- A way to increase acceleration is to change the mass
- States that Acceleration depends on the object's mass and on the net force acting on the object
- Determining Acceleration
- Third Law of Motion
- If one object exerts a force on another object, then the second object exerts a force of equal strength in the opposite direction on the first object
- For every action, there is an equal but opposite reaction
- For every action, there is an equal but opposite reaction
- Action-Reaction Pairs
- With every action, there's a reaction
- Action & Reaction forces don't cancel out because they are acting on different objects
- With every action, there's a reaction
- Momentum
- Defined as a characteristic of a moving object that is related to the mass and velocity of the object
- Momentum of a moving object can be determined by multiplying the object's mass and velocity
- Mass x Velocity
- The more momentum a moving object has, the harder it is to stop
- Defined as a characteristic of a moving object that is related to the mass and velocity of the object
- Conservation of Momentum
- Law of Conservation of Momentum
- In the absence of outside forces, the total momentum of objects that interact, doesn't change
- The total momentum of any group of objects remains the same, or is conserved, unless outside forces act on the objects
- In the absence of outside forces, the total momentum of objects that interact, doesn't change
- Law of Conservation of Momentum
- If one object exerts a force on another object, then the second object exerts a force of equal strength in the opposite direction on the first object
