Which has more inertia- a golf ball or a baseball?

A baseball!

100

What is the difference between balanced and unbalanced forces?

An unbalanced force causes an object to move. Balanced forces keep an object at rest. 

100

What is a free body diagram used for?

To show all of the forces acting on an object

100
What does a negative slope of a Velocity-Time graph tell us?

An object is slowing down

100

Which law of motion deals with balanced and unbalance forces

Newton's 1st Law

200

Explains why a it takes more force to move a loaded shopping cart that what it takes to move it when it is empty.


Newton's 2nd Law tells us that more mass= more force to move an object

200

What would happen if two equally matched teams played tug of war? Why?

The rope would not move, the forces are balanced

200

In a free body diagram, how are forces represented?

Vectors!

200

What does a steep slope on a distance-time graph represent?

Something is moving fast

200

Give a real-world example of Newton's 3rd Law

(Answers will vary)

300

What happened when you added more weight to your balloon car? Which law does this apply to?

The car did not move as far or as fast. Newton's 2nd law tells us more force is required to move an object with more mass. 

300

Name 4 different forces we have discussed

 Normal, gravity, air resistance, applied force, friction

300

If gravity pushes down on an object sitting on the floor with the force of 10 N, how much force is being applied to the object by the floor

10 N

300

How can you tell if an object is at rest on a distance-time graph?

Straight (horizontal) slope

300

The property of matter that describes an objects tendency to move in a straight line

What is 'interia'?

400


The reason grown-ups often choose the “inside” seat when riding an amusement park ride with small children, especially if it has sharp turns in one direction..


Inertia! (Newton's 1st Law)

400

How does friction affect motion?

Friction will slow an object down

400

If a force of 20N is applied to the left side of a box and a force of 50 N is applied to the right side of the box, what is the net force?

30 N to the right

400

How can you identify acceleration from a velocity-time graph?

A curved slope

400

If you push on a wall with a force of 30 N, how much force is the wall exerting on YOU?

30 N

500
Describe how all 3 of newtons laws were applied to our balloon cars

answers vary

500

Which force opposes an applied force?

Friction

500

Describe a scenario where an object would have a net force of 20 N to the right

answers vary

500

What does a curved negative slope mean on a velocity-time graph

The object is decelerating 

500

4 vehicles with different mass are moving at the same speed

A: 2000kgs

B:1000 kgs

C:1500 kgs 

D: 1200 kgs

If the same braking force is applied to all the vehicles, which car will slow down the fastest ?


Car B- 1000kgs
