Forces and Newton's Laws

A push or pull

• force
• mass
• acceleration
• net force

The sum of all forces acting on an object

• motion
• balanced forces
• unbalanced forces
• net forces

Net force is zero

• balanced forces
• unbalanced forces

The object stays at rest or stays in motion with the same speed and direction

• balanced forces
• unbalanced forces
• net forces > 0
• negative acceleration

Net forces > 0

• balanced
• unbalanced
• net forces
• negative forces

An object's motion has changed speed and/or direction

• balanced
• unbalanced
• newtons
• net force

any change in an object's motion: speeding up, slowing down, stopping, starting, changing direction

• acceleration
• at rest
• motion
• forces

movement

• motion
• at rest
• newton's
• balanced

a state of balanced forces where no motion is detected

• at rest
• forces
• unbalanced
• newton

unit of measurement for force

• Newton
• Joule
• meter
