2. The force of gravity
1. The force of energy and
2.The force of the water
The force of gravity and
2.The force of the blades1.
1. The force of the blades
2. The force of the toothpicks
If the total sum of forces on an object is anything but zero, what effect will that have on the object's motion?
The object will move.
The object won't move.
The object disappears.
What happens to the motion of an object when the forces on it are balanced?
If the object isn't moving already, it stays in its place. If it is already moving, it maintains the same speed & direction.
The object doesn't move because the forces acting on it are 100% balanced.
No one wins the tug of war.
There is continuous movement in the same speed & direction because the forces are balanced.
What happens to the motion of an object when the forces acting on it are unbalanced?
If the forces are unbalanced, the motion and/or direction of the object will change.
The object falls to the ground because it is unbalanced.
The object stops moving because of the force of friction.
Balanced and unbalanced forces don't affect the motion of an object.
What causes the water turbine to change its motion or remain at rest?
Balanced forces causes it to change its motion.
The turbine doesn't care about forces it is an inanimate object.
Unbalanced forces causes it to change its motion.
What are the two things that affect the change in motion in the water turbine?
Different matter and types of water
The different mass (amount of water) and speed of the water
Different rates of energy and blades
Two different types of energyg
Is this force balanced or unbalanced?
Balanced
Unbalanced
Which of the answer choices is not an characteristic of a balanced force?
