When an object has a net force of 0 N, it is an example of what kind of force?
Balanced
Unbalanced
Acceleration
Gravity
Planets do not twinkle because
they emit light of a constant intensity
Their distance from the earth does not change the time
They are very far away from the earth resulting in decrease in intensity of light
They are nearer to earth and hemce we recieve a greater amount of light and, therefore minor variations in the intensity are not noticeable
Which of the following is NOT an example of acceleration?
A truck slowing down for a stop sign
A motorcycle turning a corner at a consistent speed
A truck driving straight and using cruise control
A plane taking flight
Units of work (W)

Starting from the origin, a person walks 8 km east during first day, and 5 km west the next day. What is the net displacement of the person from the initial point in two days?
6 km east
3 km east
10 km west
5 km west
11 km west
What is the distance that the object travels in the first 5 seconds?
4m
5m
9m
20m
It is impossible to tell.
Two baseballs are thrown from the roof of a house with the same
initial speed, one is thrown up, and the other is down. Compare the
speeds of the baseballs just before they hit the ground.
The one thrown up moves faster because the initial velocity is up
The one thrown down moves faster because the initial velocity is
down
They both move with the same speed
The one thrown up moves faster because it has greater
acceleration
The greater the mass of an object,
the easier the object starts moving.
the greater its inertia.
the more balanced it is.
the more space it takes up.
According to the law of conservation of momentum, when two objects collide in the absence of outside forces,
velocity decreases
velocity increases
the objects have the same momentum before and after they collide.
the objects have more momentum after they collide than they did before.
Speed =
Distance ÷ Speed
Velocity ÷ Time
Distance x Time
Distance ÷ Time

If you rub two balloons with the same piece of wool cloth, the balloons will:
Be attracted to each other.
Repel each other.
Have no interaction.
Not enough information is given to determine what will happen.
Which of the following statements is NOT correct about the magnitude of the electric force between two charged objects?
It increases if one of the charges increases.
It increases if the distance between the charges increases.
It increases if both of the charges increase.
It increases if the distance between the charges decreases.
total current
and the voltage through resistor 3.
