1

What is Uniform Circular Motion?

Uniform circular motion is the motion of an object moving in a circular path at a constant speed.

New cards

2

How does velocity change in Uniform Circular Motion?

In Uniform Circular Motion, although the speed may be constant, the velocity is not because the direction is always changing.

New cards

3

What causes acceleration in Uniform Circular Motion?

Since the velocity is changing in Uniform Circular Motion, there must be acceleration.

New cards

4

What is Centripetal Force?

Centripetal force is the force that acts on an object moving in a circular path, directed towards the center of the circle.

New cards

5

What is the purpose of Centripetal Force?

Centripetal force is responsible for keeping the object moving in a circular path.

New cards

6

What is Centripetal Acceleration?

Centripetal acceleration is what turns the velocity vectors to keep the object traveling in a circle.

New cards

7

What is the formula for Centripetal Acceleration?

aęś€ = v^2/r

New cards

8

What is the formula for Centripetal Force?

F = mv^2 / r

New cards

9

What are some examples of Uniform Circular Motion?

Examples include a car around a circular track, a satellite orbiting the Earth, and a ball on a string being swung in a circle.

New cards

10

What are the four fundamental forces in physics?

The four fundamental forces in physics are the gravitational force, the electromagnetic force, the weak force, and the strong force.

New cards

11

What dominates at the largest mass and distance scales?

Gravity dominates at the largest mass and distance scales because its effects are proportional to the mass of the objects involved.

New cards

12

What is the Gravitational Force?

The gravitational force is the force of attraction between two masses.

New cards

13

What is the formula for Gravitational Force?

F = G * (m1 * m2) / r^2

New cards

14

What is the Coulomb's Law?

Coulomb's Law describes the attractive or repulsive force between two charged objects.

New cards

15

What is the formula for Electric Force?

F = k * (q1 * q2) / r^2

New cards

16

What is Gravitational Acceleration?

Gravitational acceleration is the acceleration experienced by an object due to the force of gravity.

New cards

17

What is the formula for Gravitational Acceleration?

g = G * M / r^2

New cards

18

What is the value of gravitational acceleration on Earth?

On Earth, the value of gravitational acceleration is approximately 9.81 m/s^2.

New cards

19

What happens to an object in free fall?

If an object is in free fall, the gravitational force is the only force being exerted on the object.

New cards

20

What is the formula for Gravitational Field?

g = Gm/r^2
