Motion

Question 1

Motion

Answer 1

An object in motion is changing position

Question 2

Distance

Answer 2

How far you must travel

Question 3

Displacement

Answer 3

The distance from your starting point and the direction you traveled

Question 4

Speed

Answer 4

The distance traveled divided by the time taken to travel that distance

Question 5

Average speed

Answer 5

The total distance traveled divided by the total travel time

Question 6

Instantaneous speed

Answer 6

The speed of an object at one instant in time

Question 7

Velocity

Answer 7

The speed in which it is moving and the direction of motion

Question 8

Momentum

Answer 8

The measure of how hard it is to stop an object in motion

Question 9

Energy

Answer 9

The ability to do work or cause an object to move/ change

Question 10

Potential energy

Answer 10

Stored energy because of an objects position or chemical make-up

Question 11

Kinetic energy

Answer 11

Any matter that is in motion has kinetic energy

Question 12

Law of conservation of energy

Answer 12

Energy cannot be created or destroyed, just converted into a different form

Question 13

Newton’s first law of motion

Answer 13

An object at rest tends to stay at rest and an object in motion tends to stay in motion, with the same direction and speed

Question 14

Newton’s second law of motion

Answer 14

The greater the mass of the object being accelerated the greater the amount of force needed to accelerate the object

Question 15

Newton’s third law of motion

Answer 15

For every action there is an equal and opposite reaction

Question 16

What is the formula for force

Answer 16

Force=mass • acceleration

F=ma
