Answer 2

Reference Point

Question 3

The total length of your path

Answer 3

Distance

Question 4

The distance between your initial starting point and your final end point

Answer 4

Displacement

Question 5

The distance an object moves divided by the time it took to move that distance

Answer 5

Speed

Question 6

The ratio of the distance an object moves to the time it takes for the object to move that distance

Answer 6

Average Speed

Question 7

The speed of direction

Answer 7

Velocity

Question 8

The measure of how quickly the velocity of an object changes

Answer 8

Acceleration

Question 9

How do Scientists use graphs of motion to track animals?

Answer 9

The x-axis shows the time and the y-axis shows the displacement of the animal from a reference path

Question 10

A push or pull on an object

Answer 10

Force

Question 11

Contact vs. non-contact force

Answer 11

Contact: a push or pull applied by one object to another object that is touching it.

Non-contact: a force that pushes or pulls an object without touching it.

Question 12

A contact force that resists the sliding motion between 2 object that are touching it.

Answer 12

Friction

Question 13

A non-contact attractive force that exists between all objects that have mass

Answer 13

Gravity

Question 14

The sum of the forces acting on an object.

Answer 14

Net force

Question 15

Balanced vs. Unbalanced Forces

Answer 15

Balanced - when the net force on an object is 0N the forces acting on it.

Unbalanced - When the net force action on an object is not 0.

Question 16

The tendency of an object to resist a change in motion

Answer 16

Inertia

Question 17

Forces are measured in _____, after ________ _______ who studied motion.

Answer 17

Newtons

Isaac Newton

Question 18

Newton’s ______ Law of Motion states that if the net force acting on an object is zero, the motion of the object does not change.

In other words, an object remains at rest or in constant motion unless an outside, unbalanced force acts on it.

Answer 18

First

Question 19

Newton’s _____ Law states that the acceleration of an object is equal to the net force exerted on the object divided by the object’s mass.

Answer 19

Second

Question 20

Newton’s ____ Law states that when one object exerts a force on a second object, the second object exerts a force of the same size, but in the opposite direction on the first object

Answer 20

Third

Question 21

When two objects apply force on each other, one of the forces is called the ______ force and the other is called the _______ force

Answer 21

action

reaction

Question 22

When two objects exert forces on each other

Answer 22

Force pair

Question 23

Force Pair: when two objects exert force on each other are NOT the same as ________ ________

Answer 23

Balanced forces

Question 24

Balanced forces ________ or ______ each other out because they act on the same object

Answer 24

combine or cancel

Question 25

Newton's Law ____ _____ apply to all motion in the universe

Answer 25

do not

Question 26

Newton's Law don't correctly predict the motion of very tiny objects such as _____ or ________

Answer 26

atoms or electrons

Question 27

Newton's Laws do not work for object that approach the speed of ________

Answer 27

light

Question 28

Which of Newton's Laws? When a car stops suddenly, the passengers still feel forward motion. This is due to the inertia of motion whereby the car begins to stop while the body inside is still in a state of motion.

Answer 28

First

Question 29

Which of Newton's Laws? When you turn off a table fan, the blades continue to move for some time even without electricity because of the ____ Law of Motion.

Answer 29

First

Question 30

Which of Newton's Laws? A dirty dish lying on the table will not move or get cleaned unless you apply some force and put it in the dishwasher.

Answer 30

First

Question 31

Which of Newton's Laws? When we kick a soccer ball in a specific direction, we are exerting force on the ball. The harder we kick, the more force we apply, and the farther the ball goes.

Answer 31

Second

Question 32

Which of Newton's Laws? In racing cars, engineers try to keep vehicle mass as low as possible. This means with lower mass more acceleration can be provided. If the acceleration is higher, the chances of winning the race are also increased.

Answer 32

Second

Question 33

Which of Newton's Laws? During a car accident, the force between the car and the obstacle is known as impact force. This force depends on the masses of colliding vehicles and the speed at which they are moving. This means that if a bigger and heavier vehicle moving with greater speed is involved in a collision, the intensity of the impact force will be greater.

Answer 33

Second

Question 34

Which of Newton's Laws? When you sit in a chair, you are constantly pushing on the chair with a downward force. The chair is also pushing you back with an upward force; otherwise, the chair would collapse and you would fall.

Answer 34

Third

Question 35

Which of Newton's Laws? Birds also fly using the Third Law of Motion. The wings of the bird push the air, creating an upward force which helps them move forward. Airplanes and helicopters also use this technique.

Answer 35

Third

Question 36

Which of Newton's Laws? While swimming or moving in a rowboat, when you push the water backward, there is an equal and opposite force generated which causes forward motion.

Answer 36

Third
