Flashcards
What is force?
What is force?
A push or pull, or any action that is able to change motion, measured in newtons (N).
Changing motion
Changing motion
Motion can only be changed through the action of a force.
Creating forces
Creating forces
Forces are created in many ways, such as by muscles, gravity, or air movement.
Study Notes
- Sir Isaac Newton (1642-1727) was an English physicist and mathematician.
- Newton is considered one of the most brilliant scientists.
- Before he was 30, Newton had made important discoveries in physics and invented calculus.
- Newton's three laws of motion are widely used natural laws.
- The laws explain the relationships between forces acting on an object, the object's mass, and its motion.
Force Changes Motion
- Motion can only change through the action of a force.
- In physics, hitting a ball applies a force to the ball.
- A force is a push or pull, or any action that is able to change motion.
- A golf ball will stay at rest until a force sets it in motion.
- Once moving, the ball will continue in a straight line at a constant speed unless another force changes its motion.
- Force is needed to start things moving, or to change their motion after they are moving.
- Forces can increase or decrease an object's speed or change the object's direction.
- Any change in velocity requires force.
- Forces are created in different ways.
- Muscles create force when swinging a golf club.
- Earth's gravity creates forces that pull on everything.
- The movement of air can create forces on a windy day.
- Each of these actions can create force and change an object's motion.
- Force is measured in newtons (N).
- Force is the action that has the ability to change motion.
- Without force, the motion of an object cannot be started or changed.
