1. Force as Push or Pull

Key Concepts & Definitions

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

Memory Hook

A push or pull is the common basis of force.

2. Effects of Force

★ 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.
