Forces
- What is a Force?
- Combining Forces
- Balanced Forces
- Forces have no effect
on motion of object
- Forces have no effect
on motion of object
- Unbalanced Forces
- Forces affect motion of object
- Forces affect motion of object
- Net Force
- The combination of all forces
acting on an object
- The combination of all forces
acting on an object
- Balanced Forces
- A Push or Pull
- Described by strength and direction
- Described by strength and direction
- Combining Forces
- Friction
- Why does it happen?
- When two forces rub against
each other they create friction
- When two forces rub against
each other they create friction
- Types of Friction
- Static
- When an object is not moving
- When an object is not moving
- Sliding
- When two suffices slide over each other
- When two suffices slide over each other
- Rolling
- When an object rolls across a surface
- When an object rolls across a surface
- Fluid
- When a solid moves through a fluid
- When a solid moves through a fluid
- Static
- Why does it happen?
- Gravity
- Universal Gravitation
- Every object attracts other objects to itself
- Every object attracts other objects to itself
- Factors Affecting Gravity
- Mass and Distance
- More mass equals more gravitational force
- More distance between two objects
equals less gravitational force
- More mass equals more gravitational force
- Mass and Distance
- Weight and Mass
- Mass is the amount of matter in an object
- Weight relies on gravity
- Mass is the amount of matter in an object
- Motion
- Free Fall
- Unbalanced Force
- When the only force acting
on an object is gravity
- Unbalanced Force
- Air Resistance
- Type of fluid friction that occurs when an
object gets slowed down by air
- Type of fluid friction that occurs when an
object gets slowed down by air
- Projectile Motion
- Terminal Velocity
- Free Fall
- Universal Gravitation
- Newton's Laws of Motion
- First Law
- Inertia
- Resistance to a change in motion
- Resistance to a change in motion
- Inertia
- Second Law
- Determining Acceleration
- Acceleration = Net Force ÷ Mass
- Acceleration = Net Force ÷ Mass
- Changes in Force and Mass
- More Net Force = More Acceleration
More Mass = Less Acceleration
- More Net Force = More Acceleration
More Mass = Less Acceleration
- Determining Acceleration
- Third Law
- For Every Action There Is An
Equal And Opposite Reaction
- Action-Reaction Pairs
- Action-Reaction Forces always occur in pairs
- Action-Reaction Forces always occur in pairs
- For Every Action There Is An
Equal And Opposite Reaction
- First Law
- Momentum
- Conservation of Momentum
- Unless there are outside forces, the total momentum
of two interacting objects will not change
- Unless there are outside forces, the total momentum
of two interacting objects will not change
- Momentum = Mass × Velocity
- Conservation of Momentum
- Rockets
- Rockets lift off by expelling gases
downward and this force causes an equal
and opposite reaction on the rocket
- Rockets lift off by expelling gases
downward and this force causes an equal
and opposite reaction on the rocket
- Satellites
- An object that orbits
other objects in space
- Centripetal Force
- A force that causes an object to
move in a circular path
- A force that causes an object to
move in a circular path
- Satellites in orbit around Earth are falling but
travel around because Earth is curved
- An object that orbits
other objects in space
