In the absence of a net external force, the linear momentum of a body, or of a system of bodies, is always conserved. Look at the definition of force: Playing billiards is a good example. We will not study angular momentum.

Gravitation Newton and Galileo both believed that in the absence of air resistance, all bodies falling to Earth have the same acceleration. We call the acceleration with which a body falls to Earth, the acceleration of gravity and use the symbol g to denote it.

It is fairly constant over the surface of the Earth, but decreases with altitude as we shall see. When the air resistance Fair equals the force of gravity Fgravity, the body reaches its terminal speed or velocity. The total force is then zero, and there is no more acceleration, so the speed is constant.

Air resistance tends to be proportional to speed. Direction is towards center of Earth. If our mass is kg, what is our weight?

The vertical speed changes due to gravity, but the horizontal speed is constant. Newton's Law of Universal Gravitation There exists an attractive interaction between any two material bodies in the universe, and the magnitude of the force on each body is directly proportional to the product of the masses of the bodies and inversely proportional to the square of the distance between their centers.

Newton figured out that the same force that causes an apple to fall to the ground from a tree is the same force that keeps the moon in its orbit. He worked out what the relationship must be.

The direction of the force is along the line between the masses.

The force is attractive.

In this lab, we will observe simple harmonic motion by studying masses on rutadeltambor.com a quantity with a magnitude only Scalar a size or amount with units Magnitude We will write a custom essay sample on Physics Sections / Scalar & Vector Quantities and Linear Motion or any similar topic only for you Order now a quantity with magnitude and direction Vector a rutadeltambor.com Momentum as a Vector Quantity.

Momentum is a vector rutadeltambor.com discussed in an earlier unit, a vector quantity is a quantity that is fully described by both magnitude and direction. To fully describe the momentum of a 5-kg bowling ball moving westward at 2 m/s, you must include information about both the magnitude and the direction of the bowling rutadeltambor.com://rutadeltambor.com the sum of two or more vectors resultant vector vector addition when vectors are collinear R=A+B We will write a custom essay sample on AP Physics 1 Vector Addition and Subtraction or any similar topic only for you Order now used to find the sum of perpendicular vectors R^2=A^2+B^2 used rutadeltambor.com Motion, Force, and Gravity.

Speed describes how fast a body moves: measured in feet/second, miles per hour, meter/second, etc. Instantaneous speed describes the speed at any instant.. Average speed describes the speed over some time period..
