Study Notes
- A force is indicated when an object changes shape or motion.
- Forces can be categorized as push, pull, lift, or press.
Types of Forces
- Contact force happens when an object directly touches another.
- Non-contact force happens when objects exert force without touching.
- An example of contact force: A baby pushes a toy car by hand.
- An example of contact force: A player kicks a ball.
- An example of non-contact force: Earth's gravity makes an apple fall.
Force and Motion
- Applying force to a stationary object can make it speed up.
- Applying force can cause an object to deform and change its motion.
- A spring shortens when compressed, showing the effect of compressive force.
Examples of Forces
- A weightlifter exerts a lifting force on a barbell.
- A goalie uses force to change the motion of a ball, causing deformation and stopping it.
Additional Exercises
- Kicking a stationary ball makes it move.
- Rubbing a plastic ruler on cloth and using it to pick up paper bits demonstrates a force.
- A force is applied when object A pushes or pulls object B.
