Newton's Law
What does Newton's first Law State?
Objects in motion stay in motion unless acted on by a force.
What is the unit of force?
Newton(N)
What is the formula for speed?
speed=distance/time
What type energy is stored?
Potential
What type of graph shows how something changes over time?
line graph
Which of Newton’s laws involves action and reaction?
Newton's Third Law.
What causes a change in motion?
A Force.
What happens to speed when distance stays the same but time decreases?
Speed increases
What are the units for force?
N
What do you label the two lines on the graph?
x-axis and y-axis
What does Newton’s Second Law tell us?
Force equals mass times acceleration (F = m × a).
What is the Formula for speed?
Speed = distance divided by speed.
What is velocity?
Speed in a certain direction
What type of energy is stored in a stretched rubber band?
Potential energy
If the line on a graph goes up, what does that mean about speed?
increases
Give an example of Newton’s First Law in real life.
A soccer ball stays still until kicked.
If you push a cart with more force, what happens to its acceleration?
It Increases.
How can you tell if an object is accelerating on a speed-time graph?
The line slopes upward
What type of energy is shown when the rubber band snaps back?
kinetic energy
If the line is constant or straight what does that mean?
No changes in the data
What happens when forces on an object are balanced?
The object’s motion does not change.
What type of energy is related to motion?
Kinetic Energy
If a car travels 60 km in 2 hours, what’s its speed?
30 km/h
Explain the relationship between mass and force in F = m × a.
More mass needs more force to move the same acceleration.
Why do we label and title the graph?
To show the relationship over time
