Forces
This happens when an item has two forces acting on it and the item moves.
What are balanced forces?
A pen falls to the ground thanks to this type of force.
What is a noncontact force?
This tells you how fast something is going in a specific direction.
What is velocity?
This tells us an item at rest does not want to start moving, while a moving item does not want to rest. This describe this law.
What is Newton's 1st Law?
This happens when two forces are acting on an item and the stronger force causes the item to move.
What are unbalanced forces?
Kicking your foot off the ground while on a skateboard makes you roll forward. This is an example of this type of force.
What is a contact force?
This tells you about the change of speed an item goes through over time.
What is Acceleration?
This law tells us every action taken will have an opposite and equal reaction.
What is Newton's 3rd Law?
Magnetism an Gravity are both this type of force.
What is Noncontact Force?
In a tug of war match, you see this force in action when one side pulls the other.
What is an unbalanced force?
This tells you how much distance has already been covered over the timeframe it took them to get there.
(Think of mph)
What is speed?
This tells us that an item's mass directly affects it inertia.
What is Newton's 2nd Law?
Tires rolling on the road, pushing your feet off the ground to jump, and many other actions relate to this type of force.
What are contact forces?
A magnet is lifting a piece of metal, but gravity is also pulling on the metal, as a result it does not move.
What are balanced forces?
A car accelerates from 15mph to 30mph in 3 seconds. This is its acceleration.
What is an acceleration of 5mph/s?
What is a net force of 75 Joules?
This is required for motion to be observable.
What is a reference point?
You and your friend go to kick a ball at the same time, as a result the ball does not move. This is an example of these TWO types of forces
What are balanced contact forces?
A car traveled 30 miles over a 3 hour drive due to bad traffic. This is the car's speed during the trip.
What is 10mph?
Think about the Bill Nye video for this one. What did he use to push the train? What happened the second time he used the items to push the train?
Bill Nye used a little toy person to push the train, the second time he used two little toy people.
