What are balanced forces?
Forces that are equal in size but opposite in direction, resulting in no change in motion.
What are unbalanced forces?
Forces that are not equal and opposite, causing a change in motion.
What is Newton's First Law of Motion?
An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an unbalanced force.
What is meant by the "state of motion" of an object?
It refers to whether the object is at rest or moving, and its speed and direction.
What is the formula for average speed?
Average Speed = distance/time
How do balanced forces affect motion?
They keep an object at rest or moving at a constant velocity
How do unbalanced forces affect motion?
They cause an object to accelerate, decelerate, or change direction.
How does inertia relate to Newton's First Law?
Inertia is the tendency of an object to resist changes in its state of motion.
How can you determine the state of motion of an object?
By observing its position and comparing it to other objects over time.
What is velocity?
Speed in a specific direction
Give an example of balanced forces in everyday life.
A book resting on a table.
They cause an object to accelerate, decelerate, or change direction.
A soccer player kicking a ball.
Why is it important to understand Newton's First Law?
It helps explain how forces affect motion in the world around us.
What factors can change the state of motion?
Forces acting on the object, such as pushes, pulls, and friction.
What is a saturated solution?
When a solution has reached it's mass capacity to dissolve a solute
What happens to an object at rest when balanced forces act on it?
It remains at rest.
What happens to a moving object when unbalanced forces act on it?
It changes speed or direction.
What are real-life examples of Newton's First Law?
A passenger lurching forward in a car that suddenly stops.
How do balanced and unbalanced forces work together to change motion?
Balanced forces maintain motion, while unbalanced forces create changes in speed or direction.
How many atoms of oxygen are in the formula 2(H₂)4O8
There are 32 atoms of oxygen
Explain how balanced forces can affect a moving object.
If balanced forces act on a moving object, it continues moving at the same speed and in the same direction.
Explain how unbalanced forces can change the direction of an object.
An unbalanced force can push or pull an object, altering its path.
Explain how friction can affect Newton's First Law.
Friction is an unbalanced force that can slow down or stop moving objects.
Describe a scenario where both balanced and unbalanced forces are present.
A car driving at a constant speed (balanced) and then accelerating when the driver presses the gas pedal (unbalanced).
