1. Force as Push or Pull

Key Concepts & Definitions

  • Force: a push or pull on an object resulting from the objectโ€™s interaction with another object

Memory Hook

A push or pull is the common basis of force.

2. Effects of Force

โ˜… Must-know

  • A force may:
    • make an object move from rest
    • change the speed of an object
    • change the direction of motion of an object
    • change the shape of an object
    • cause some or all of these effects

Further detail

  • Hitting a moving ball with a bat can change the direction of the ball, while pressing an inflated balloon can change its shape.

Memory Hook

MSDS: Move, Speed, Direction, Shape.

3. Force and Interaction

Key Concepts & Definitions

  • Interaction: At least two objects must interact for a force to come into play.

โ˜… Must-know

  • The SI unit of force is the newton, whose symbol is N.
