Question 1

what is acceleration?

Answer 1

Acceleration is the change in velocity per second

Question 2

what is speed?

Answer 2

Velocity equals distance over time

Question 3

What is attract?

Answer 3

To draw a force to cause it to unite or pull

Question 4

What is balanced forces?

Answer 4

When two forces are together and are same in size but act in different directions.

Question 5

What is deceleration?

Answer 5

Deceleration is the term used for acceleration that causes an object to slow down.

Question 6

What is distance?

Answer 6

how far you cover.

Question 7

Name one type of energy

Answer 7

kinetic energy

Question 8

What is electrostatic force?

Answer 8

relating to stationary electric charges or fields as opposed to electric currents

Question 9

What is force?

Question 10

What is force diagram?

Answer 10

A force diagram is simply a diagram showing all the forces acting on an object, the force’s direction and its magnitude. It is a simplification of the picture that shows just the forces.

Question 11

What is force field in science?

Answer 11

In physics a force field is a vector field that describes a non-contact force acting on a particle at various positions in space. Specifically, a force field is a vector field , where is the force that a particle would feel if it were at the point

Question 12

what is friction force?

Answer 12

Between two hard surfaces, the kinetic friction is usually somewhat lower than the static friction, meaning that more force is required to set the objects in motion than to keep them in motion. See also drag. The American Heritage® Science Dictionary.

Question 13

What is gradient?

Answer 13

In mathematical terms, gradient is simply the slope of a linear equation (i.e. y = mx+b), where m is equal to “the rise over the run”. Gradient can be determined easily if you have a known change in field value (temperature, elevation, distance, etc.) taking place over a known distance.

Question 14

What is gravity?

Answer 14

Gravity is a force which can pull or push towards each other.

Question 15

What is lubricant?

Answer 15

A substance used for lubricatin​g an engine or component, such as oil or grease

Question 16

What is magnetism

Answer 16

A physical phenomenon produced by the motion of electric charge, which results in attractive and repulsive forces between objects.

Question 17

What is mass?

Answer 17

mass definition. In physics, the property of matter that measures its resistance to acceleration. Roughly, the mass of an object is a measure of the number of atoms in it. The basic unit of measurement for mass is the kilogram

Question 18

What is newton?

Answer 18

The SI derived unit used to measure force. One newton is equal to the force needed to accelerate a mass of one kilogram one meter per second per second. See also joule. Newton, Sir Isaac 1642-1727. English mathematician and scientist

Question 19

North Pole

Answer 19

either of two variable points on the earth’s surface towards which a magnetic needle points, where the lines of force of the earth’s magnetic field are vertical. North Pole in Science Expand. North Pole. The northern end of the Earth’s axis of rotation, located at 90° north latitude at a point in the Arctic Ocean

Question 20

What is reaction time in science?

Answer 20

The time elapsing between the beginning of the application of a stimulus and the beginning of an organism’s reaction to it

Question 21

What does repel mean in science?

Answer 21

.

Question 22

What is S.I units

Answer 22

The seven SI base units and the interdependency of their definitions. Clockwise from top: kelvin (temperature), second (time), metre (length), kilogram (mass), candela (luminous intensity), mole (amount of substance) and ampere (electric current).

Question 23

South Pole

Answer 23

For most purposes, the Geographic South Pole is defined as the southern point of the two points where the Earth’s axis of rotation intersects its surface (the other being the Geographic North Pole).

Question 24

What is speed?

Answer 24

rapidity in moving, going, traveling, proceeding, or performing; swiftness

Question 25

What is ticker timer?

Answer 25

The ticker timer makes dots on a paper tape every fiftieth of a second. So if a piece of tape is pulled through the timer for a second there will be 50 dots on it. Since the spaces between the dots take such a short time (1/50 s) the ticker timer is a very useful instrument for measuring short intervals of time

Question 26

What is time?

Answer 26

A point of time as measured in hours and minutes past midnight or noon

Question 27

What is unbalanced forces?

Answer 27

Unbalanced forces are forces that cause a change in the motion of an object. Learn more about how to identify balanced and unbalanced forces through several examples and test your knowledge with quiz questions.

Question 28

What is velocity?

Answer 28

Velocity is speed in a given direction
