... Weight and Mass • Mass is sometimes confused with weight. • Mass is a measure of the amount of matter in an object; weight is the measure of the gravitational force exerted on an object. • The force of gravity on a person or object at the surface of a planet is known as weight. • So, when you step ...

Newton`s Laws of Motion
... Inertia Galileo came up with the definitions of FORCE and FRICTION. Force is any push or pull. Friction is the name given to the force that acts between materials that touch as they move past each other. Galileo was concerned with how things move rather than why they move. Galileo stated that ev ...

grade 9 physics notes
... 1. Gravitational force is an attractive force between objects with mass. It is greater if the mass of the object or the planet is more. 2. Friction is the resistive force acting between two surfaces in motion. It is greater at higher speeds. 3. Air resistance is the frictional force exerted by air o ...

... • Example: you are in a fast-moving car and the brakes fail. Would you want to stop by hitting a brick wall or hit a haystack and move until you eventually come to rest? • By hitting the haystack you extend the contact time (time in which your momentum is brought to zero by opposing forces) • Force ...

... A force can be a push or a pull. For example, when you push open a door you have to apply a force to the door. You also have to apply a force to pull open a drawer. You cannot see a force but often you can see what it does. Forces can change the speed of something, the direction it is moving in or i ...

Lecture Notes for Section 13-6
... When an airplane executes the vertical loop shown above, the centrifugal force causes the normal force (apparent weight) on the pilot to be smaller than her actual weight. How would you calculate the velocity necessary for the pilot to experience weightlessness at A? ...

Non-sticky collisions
... around Earth rather than onto it. Once it has entered a stable orbit, a satellite does not need fuel. It continues to move ahead due to its inertia. At the same time, gravity continuously changes the satellite’s direction. Most satellites are launched at a speed of about 7,900 m/s. That’s more than ...
