Any force that causes an object to follow a circular path

What is Centripetal Force?

100

The formula for centripetal acceleration

ac =

 v^2/(r)

100

The units for acceleration

What are m/s2

100

According to this law, the acceleration of an object depends on its mass and the net force acting on it.

What is F = ma

100

The acceleration of an object moving with a constant speed of 30m/s on a circular track of radius 150m. 

6 m/s2

1) ATTENNG

2) EEOYSNTPH

What are tangent and hypotenuse

200
The number of rotations or revolutions per unit of time
What is Frequency?
200

An object moves in a circular path at a constant speed. Compare the direction of the object’s velocity and acceleration vectors.

What is perpendicular to each other.

200

The units of measurement of force

What are Newtons (N)

200
This Newton Law of Motion supports the idea that an object will always continue in a straight line path
What is Newton's First Law of Motion (Or Law of Inertia)..."An object in motion..."
200

The mass of an object that is traveling at acceleration of 20m/s2 and a force of 10,000N

What is 500 kg?

m= F/a = 10,000 / 20 

m= 500 kg

LTPRNCAEITE   ERFCO

What is centripetal force

300
The time it takes for one full rotation or revolution of an object
What is Period?
300

These 2 variables are perpendicular to one another in centripetal motion.

What are velocity and acceleration

300

The units of measurement of Energy

What are Joules

300

This is the name of the pulling force transmitted through a string, rope, or cable when it is tight.

What is tension?

300

The tangential acceleration of a race car on the starting line- accelerates at a uniform rate to a speed of 45m/s in 15s, moving on a circular track of radius 500m.  

3.0 m/s2

EERFCOTN  (2 words)

What is Net Force

400
An object in circular motion follows this path if the centripetal force is removed.
What is straight line path OR tangent to the direction of motion?
400

The direction of an objects acceleration moving in a circular path at a constant speed. 

What is Inward, or toward the center of the circular path

400

What Joules really are

kg xx m^2/(s^2)

400

This force always acts perpendicular to a surface and supports an object resting on that surface.

What is the normal force

400

The acceleration of an object moving with a constant speed of 30m/s on a circular track of radius 150m. 

6m/s2

1) YTMEREOG

2) LNIRPPRATOOO

What are geometry and proportional

500
Increasing these 2 variables will increase the tangential speed of an object.
What are radius and force? (also accept frequency)
500

Why it is possible for an object moving with constant speed to accelerate 

Speed is constant, 

but the direction of velocity is changing

500
Isaac Newton created this branch of mathematics to calculate the motion of the falling moon
What is Calculus?
500

These are the two variables or things in a physical space that determine what the acceleration of an object will be

What are Force and Mass?

500

The mass of a car negotiating a flat curve of radius 50m with a speed of 20m/s.  The centripetal force of friction is 1.2x104N.
