Graphs
As distance increases, the force value decreases. What can you conclude?
The force becomes weaker as distance increases.
What happens to an object when forces are balanced?
Its motion does not change.
What type of energy does a moving object have?
Kinetic
Which type of wave requires a medium to travel?
Sound
Why is friction sometimes helpful?
It allows objects to grip surfaces.
What does this most likely mean?
A force is acting to slow the object down.
Which force slows down a moving object when it rubs against another surface?
Friction
What type of energy is stored due to position or height?
Potential
Which of type of wave can travel through empty space?
Light
Why does an object eventually stop moving if no force keeps pushing it?
Friction or air resistance slows it down.
What does this graph depict?
The force is stronger when the objects are closer together.
Why does a heavier object usually accelerate less than a lighter object when pushed with the same force?
It has more mass and requires more force to change its motion.
As a roller coaster goes down a hill, which energy increases?
Kinetic
The wave speed increases
Why is lightning seen before thunder is heard?
Light travels faster than sound.
A student claims that force and distance are not related.
Based on the graph, where force steadily decreases as distance increases, is this claim correct? Why or why not?
No. The graph shows a clear relationship between force and distance.
Which of Newton's Laws explains why a swimmer moves forward when pushing water backward?
Newton's 3rd Law
Why does a fast-moving object have more kinetic energy than a slow-moving one?
Because kinetic energy depends on speed.
Why can you hear thunder but not see sound waves?
Sound waves are not visible and require a medium
If 2 objects are pushed with the same force, what factor affects how much they accelerate?
Mass (weight)
What can you conclude from this graph?
The force weakens as distance increases, but changes more slowly at larger distances.
An object moves at a constant speed even though a force is applied. What must also be true?
An equal force is acting in the opposite direction.
During a collision, what happens to energy?
How do waves transfer energy without transferring matter?
Particles vibrate but return to their original position
Why are graphs useful in science?
They help show patterns and changes over time.
