A contact for is those applied when one object actually touches another. What is an example of this?

• Gravity

• Magnetism

• Friction

• Electricity

What is a balanced force? (With an example)

• Opposite in strength and equal in direction (ex. Book resting on shelf)

• Equal in strength and equal in direction (ex. Book resting on shelf)

• Opposite in strength and opposite in direction (ex. Book resting on shelf)

• Equal in strength and opposite in direction (ex. Book resting on shelf)

What is an unbalanced force? give an example

• Not in equal in strength
  (ex. Taking book off shelf)

• Equal in strength
  (ex. Taking book off shelf)

• Equal in strength and opposite in direction (ex. Book resting on shelf)

• Opposite in strength
  (ex. Book falling off shelf)

What happens if the Net Force is the SAME?

• Net force is the sum of the forces

• Net force is the difference in strengths

• Net force is balanced

What happens if the Net Force is the OPPOSITE

• Net force is balanced

• Net force is the sum of the forces

• Net force is the difference in strengths

What happens if the Net Force is ZERO

• Net force is the sum of the forces

• Net force is balanced

• Net force is the difference in strengths
