Introduction to fources

Question 1

(One on Quiz) GRAVITY

Answer 1

A force of attraction between objects that is due to their masses and that decreases as the distance between the object increases

Question 2

Newton

Answer 2

The SI unit of force. It is equal to the force that would give a mass of one kilogram an acceleration of one meter per second per second, and is equivalent to 100,000 dynes.

Question 3

Acceleration

Answer 3

A vehicle’s capacity to gain speed within a short time.

Question 4

Velocity

Answer 4

The speed of something in a given direction.

Question 5

Air resistance

Answer 5

Air resistance is the frictional force air exerts against a moving object. As an object moves, air resistance slows it down. The faster the object’s motion, the greater the air resistance exerted against it.

Question 6

Force

Answer 6

Strength or energy as an attribute of physical action or movement.

Question 7

Hang time

Answer 7

the number of seconds during which a punted ball is in the air.

Question 8

Launch angle

Answer 8

Along with ball speed, launch angle is a primary component to determining the height and distance of a shot. Every golfer should be fitted to achieve the optimal balance of launch angle and spin rate based on their club speed and ball speed.

Question 9

Projectile motion

Answer 9

And an object which is thrown upward at an angle to the horizontal is also a projectile (provided that the influence of air resistance is negligible). A projectile is any object that once projected or dropped continues in motion by its own inertia and is influenced only by the downward force of gravity.

Question 10

Trajectory

Answer 10

The path followed by a projectile flying or an object moving under the action of given forces.

Question 11

Vector

Answer 11

A quantity having direction as well as magnitude, especially as determining the position of one point in space relative to another.
