MOTION, FORCE, GRAVITY EOC REVIEW

SPEED How fast something moves is SPEED Speed is the distance an object travels in a certain period of time.

VELOCITY Hurricanes, pilots, and boat captains need this. In order to completely describe the motion of an object, we need to include not only the speed of the object, but also the direction!

ACCELERATION Changing Speed Units: m/s2 How fast the speed is changing. Units: m/s2 Velocity per second meters/second per second

WHAT CAUSES THINGS TO MOVE? FORCES! What is a force? A push or a pull that one body exerts on another.

BALANCED FORCES Balanced forces are opposite and equal act in opposite directions and cancel each other out no motion occurs for the cart.

NEWTON’S FIRST LAW LAW OF INERTIA An object at rest stays at rest and an object in motion stays in motion until acted on by a net external force.

NEWTON’S SECOND LAW The force on an object equals the mass of the object times the acceleration of the object. In other words, a force causes a mass to accelerate. EQUATION: Force = mass x acceleration EQUATION: F = ma UNITS: kilogram x meter/second2 = Newton, N

NEWTON’S SECOND LAW

FORCE PROBLEMS What force is needed to give an object with a mass of 25.0 kg an acceleration of 15.0 m/s2 ? Formula F = ma Given: m = 25.0 kg a = 15.0 m/sec² F = (25 kg)(15 m/sec²) F = 375 kg•m/sec² = 375 N Unknown: F = ?

NEWTON’S THIRD LAW OF MOTION LAW OF ACTION-REACTION For every action force, there is an equal and opposite reaction force. Every action has an equal and opposite reaction.

GRAVITY Gravitational Force is an attractive force between all objects in the universe. The amount of GRAVITATIONAL FORCE between objects depends upon their: Masses (greater mass means more gravity) Distance apart (greater distance means less gravity)

STRONG FORCE Holds the protons and neurons together in the nucleus. Remember that protons want to repel each other.

THREE TYPES OF FRICTION Static Friction: The frictional force that prevents two surfaces from sliding past each other. Sliding Friction: The force that opposes the motion of two surfaces sliding past each other. Rolling Friction: The frictional force between a rolling object and the surface it rolls on.

WEIGHT AND MASS Weight and mass are not the same. Weight is a force and mass is a measure of the amount of matter an object contains. Weight and mass are related. Weight increases as mass increases. Force (weight) = mass x accel. due to gravity (9.8m/s2) Unit: Newton, N
