AP Physics 1- Gravity and Harmonic motion

What is true about all objects with mass?

All massive objects attract each other with a gravitiational force.

What is the equation for gravitational force of one object on anoter, Fg?

Fg= GM1M2/d^2 where d is the distance between the centers of the two objects and G is the gravitiational universal constant.

What is the equation for gravitational field g near an object of mass M?

g= GM/d^2 where where d is the distance between the objects center and place of consideration.

What is the weight of an object near a palnet.

The weight of an object near a planet is given by mg, where g is the gravitational field due to the planet at the objects location.

What is the free fall acceleration near x planet?

The gravitiational field near a planet is always equal to free-fall acceleration.

How is gravitational mass measured?

Gravitational mass is measured by measuring an objects weight using weight= mg.

How is inertia mass measured?

Inertia mass is measured by measuring the net force on an object, measuring the objects acceleration, using Fnet=ma.

What is true about all experiments with gravitational and inertia mass.

In all experiments ever performed, gravitational mass is equal to inertial mass.

An object in simple harmonic motion makes a position time graph in what shape?

Sin function.

The equation for simple harmonic emotion for position as a function of time is?

x=Acos(2πft)

An object in simple harmonic motion experiences a net force that does what two things?

the magnitude increases a linear function of distance from the equilibrium position and has a direction that always points back toward the equilibrium position.

Amplitude is?

The max distance from the equilibrium position reahed by the object in simple harmonic motion.

Period is?

The time for an object ot complete on vibration. Seconds per oscolation.

Frequency is?

How many entire vibrations an object makes each sound. Oscolations per second.

Period of mass on a spring is?

T=2π√m/√k

Period of a pendulum is?

T=2π√L/√g

Average speed of an object in simple harmonic motion is?

4 amplitudes per second.
