a push or a pull that can change the motion of an object
force
100
What is the definition of a balanced force?
- All forces acting on an object are equal
- results in the object not moving or the object moving at a constant speed

What does the arrow represent in this model?
The arrows represent the unbalanced force exerted on the hockey puck by the stick.

What place value is the 2 in: 41.241
What is the tenths place.
200
the amount of matter that makes up an object
mass

What is the definition of an unbalanced force?
- When forces acting on an object are not equal
- results in the object changing motion

The model shows a person pushing a cart weighing about 1000 kg (about 2200 pounds). How much force do you predict will be required to push this cart?
A. Small
B. Medium
C. Large
I would predict that a large force would need to be exerted by the man to get the cart to start moving. I know this because objects with larger masses will need to experience a greater force to change their motion than an object with a smaller mass.

A soccer player kicks a soccer ball. What force made the soccer ball move?
An unbalanced forced caused the soccer ball to move.

Use the model to help you answer the question: Which chair(s) experienced the strongest force when it was pushed? How do you know?
All three chairs experienced the same strength force because they changed speed by the same amount.
300
Define the word "Friction"
What is a force that acts on an object when it rubs against another object or material.
300
Which of these numbers are the largest? 23.524 23.5 23.6
What is 23.6
400
speed in a particular direction
velocity
400
What force causes all objects to start moving?
Unbalanced forces cause objects to start moving.
400
What do the lines on the car represent?
The lines behind the car represent velocity.
400
Define the word "Gravity"
What is A force where one object pulls another object. Because of the gravity of the Earth, we are pulled toward the Earth.

collision

Using the model, how would you expect the man's velocity to change after her lets go of the red strap?
I would expect the man's velocity to increase after he lets go of the red strap. The strap will act as an unbalanced force causing the man to fly in the air. I know that the man's velocity will increase because he will be moving and have kinetic energy.
