Physic Terms - Fly Casting

Question 1

What is speed?

Answer 1

How fast an object is moving

Question 2

What is velocity?

Answer 2

Speed in combination with the direction of motion of an object

Question 3

What is Acceleration?

Answer 3

The rate of which velocity changes overtime it may be positive negative or zero

Question 4

What is positive acceleration?

Answer 4

An increase the velocity of an object. Commonly referred to as acceleration.

Question 5

What is negative acceleration or deacceleration.

Answer 5

A decrease in the velocity of an object.

Question 6

What is constant acceleration?

Answer 6

Velocity that changes at the same rate over time.

Question 7

What is constant velocity?

Answer 7

Acceleration that is zero.

Question 8

What is force?

Answer 8

A push or pole on an object.

Question 9

What is torque?

Answer 9

A force that can cause an object to change its rotation about an axis

Question 10

What is mass?

Answer 10

The amount of matter or substance that makes up an object.

Question 11

What is weight?

Answer 11

The result of the force of gravity acting on a mass.

Question 12

What is work?

Answer 12

The energy transferred to or from an object, computed as force multiplied by the distance over which it is applied.

Question 13

What is energy?

Answer 13

The capacity of an object to do work. Forms of energy include

• Potential or stored energy;
• Kinetic, or working energy, computed as half an objects mass multiplied by the square of its velocity.

Question 14

What is momentum?

Answer 14

An objects momentum is its mass multiplied by its velocity.

Question 15

What is impulse?

Answer 15

The momentum transferred two or from an object:
computed as force multiplied by the time over which it is applied.

Question 16

What is power?

Answer 16

A measure of the rate at which work is done, or at which energy is transferred;
* computed as work done per unit of time.

Question 17

What is Newton‘s first law of motion - Inertia?

Answer 17

An object will continue its current motion or lack thereof until some net force causes its speed or direction of movement to change.

Question 18

What is new Newton‘s Second Law of Motion - Force?

Answer 18

The acceleration of an object is directly proportional to the net force acting on it.

Expressed as: Force equals Mass times Acceleration.

Question 19

What is Newton’s Third Law of Motion - Action/Reaction.

Answer 19

For every action, there is an equal and opposite reaction.

Question 20

What are the three Newton’s Law of Motion we are most concerned about?

Answer 20

Inertia: First Law
Force: Second Law
Action/Reaction: Third Law
