Speed
What is distance divided by time?
How many forces work on an object at all times?
What is two forces?
There is a box. Anne decides to push it but it doesn't move. She gets her friend Sophie to help her. They both push. What will happen to the motion of the box now?
What are the three ways in which your motion or acceleration can change?
What is speed up, slow down, and change direction?
I have a pineapple, piano, and pen in my house. When I drop them, they will all fall to the Earth. Which object will have the most gravitational pull?
What is the piano? It has more mass and therefore more gravitational pull.
What is it when an object moves the same distance per time?
What is constant speed?
A little boy is pedaling his bicycle forward but a large gust of wind is pushing back on him. What will happen to his motion?
What is the wind will cause the boy to slow down because there is a force pushing in back?
What is the difference between balanced and unbalanced forces?
What is balanced forces are when two objects have the same force on them and doesn't move because it is equal, whereas, unbalanced forces is when two objects don't have equal forces on them and it causes one of the forces to cause the object to move.
How would you define motion?
What is an object moves from one position to another position? or what is an object moves pass a reference point?
If I drop a ball and a piece of paper, why does the piece of paper want to land last?
What is the extra surface area of the paper makes the paper have air resistance that slows down its motion compared to the ball?
The race car is moving fast across the track. The pit crew clocked him at going 50 meters in 5 seconds. What is the speed of the race car according to the pit crew?
What is the speed of the race car is 10 meters per second?
One boy is behind a child and the other boy is behind the parent as they are pushing them on a swing. They are using about the same force to push the parent and child. Which describes what will happen when they push the parent and child on the swing?
What is the child will be pushed further on the swing and fly higher. The parent will not move as much on the swing.
Which force is a non-contact force? Which force is a contact force?
Pick from these two. Friction or Gravity.
They must be right to get points.
What is friction is a contact force? What is gravity is a non-contact force?
If there is no force acting on the object, what will the object do?
What is the object will stay at rest?
If Maria and Joe want to roll a toy car as fast as they can across a surface, what material should they use the toy car on? Ice, Carpet, Rough Wood? Why?
What is they should roll the toy car across ice because it is smooth and slippery- there is no or less friction?
What is the speed of this train? The train goes 800 miles in 4 hours.
What is the speed of the train is 200 miles per hour?
Steve is pushing a cart with 3 books so it just reaches the end of the track. He puts 4 more books onto the cart. What must Steve use next time so that the cart with 7 books will reach the end of the track?
What is Steve must use more force to move 7 books?
What tool do you use to measure force?
Force is measured in __________________.
Must answer both to get your points.
What is we use a spring scale to measure force? What is force is measured in Newtons?
What is it called when an object can't stop? for example, if a planet is spinning fast, it will have a lot of this?
What is inertia?
What is the difference between mass and weight?
Mass is ______________.
Weight is __________ + ____________
What is mass is the amount of matter and weight is the mass plus the amount of gravity pushing down on the mass?
On a distance time graph, how can you tell an object goes faster or slower?
What is on a distance-time graph if the line is steeper, that measure the person or object travelled more distance per time?
I have a heavy softball, light dodgeball, and a kickball. If I push them with the same force, which one would have the most acceleration? Which one would have the least acceleration? Why?
What is the light dodgeball will have the most acceleration? What is the heavy softball will have the least acceleration because it has the most mass? The kickball would be in the middle.
How does force influence an object that has a lot of mass?
What is the force doesn't influence the motion of this large mass object? It will have little to no acceleration.
If a toy car is moving across the floor already and no forces are influencing it, what will happen to its speed?
No friction, no air resistance, NO FORCES!
What is the toy car will have a constant speed and keep going at the same speed. It will not speed up or slow down.
What makes Jupiter different than a smaller planet like Mars as far as mass? Hows does Jupiter and Mars deal with gravity?
What is Jupiter has more mass and more gravity acting on it compared to Mars?
