Motion Flashcards
The worded formula for the 2nd law of motion?
Force= mass x acceleration
3 ways to reduce friction?
- Make it smooth
- Ball bearings
- Lubricants
How do I know if I’m moving or if something else is moving?
Stationary point
Which is the easier friction to move?
Kinetic Friction
Where would a ball keep moving and never stop?
Space
Why would the ball keep moving there? (Space)
No resistance
The REALLY long one
Five blocks
The scientific words for the 1st law of motion?
Inertia and Momentum
To get out of my chair in accordance to the third law of motion?
Push down
For your car to go forwards what must happen for it to move according to the 3rd law of motion?
Push backwards
Mathematic terms for slowing down?
Negative acceleration
Scientific word for slowing down?
Deceleration
Combined force?
Net force
If it doesn’t move it’s called?
Balanced force
The formula for speed
Distance/Time
Ways to increase friction?
- Make the surface rougher
- Increase the force
What is Instantaneous speed?
Whatever speed your going at the present moment
What is Displacment?
Distance from beginning point to end point ignoring everything else
What is Average speed?
Total distance/ Total time to travel
What is acceleration?
A change in speed
What does a triangle in math or science mean?
Delta
What is force?
Something that moved an object
What is balanced force?
When the object doesn’t move because all the forces combined = 0
What is Friction?
A force that opposes motion
What is static friction?
Friction between two stationary surfaces
