FORCES (Gravity, Friction, Mass)
This force change the direction of a moving object.
what is a push or a pull?
This tells how fast an object is moving.
What is speed?
The type of motion that is shown on this graph:
What is an increasing rate of speed?
Mixing sand and water creates this type of matter.
What is a mixture?
Heating ice causes it to do this.
What is melt?
This force slows down moving objects when two surfaces rub together.
What is friction?
If an object travels 10 meters in 5 seconds, this is its speed.
What is 2 meters per second?
Jimmy drove 150 miles in 3 hours.
What was his average rate of speed?
What is
50 miles per hour?
This happens when no new substance is formed after mixing.
What is a physical change?
Cooling water causes it to do this.
What is freeze?
When friction increases, an object’s motion usually does this.
What is slows down?
This tool helps us measure distance during a motion investigation.
What is a ruler or measuring tape?
Using this graph, this is how many seconds the student stopped walking.
What is
2 seconds?
Mixing baking soda and vinegar produces bubbles, showing this.
What is a new substance/chemical change?
Heating metal usually makes it do this.
What is expand?
Adding more mass to an object usually makes it harder to do this.
What is change its motion / speed it up / stop it?
When distance stays the same but time decreases, speed does this.
What is increases?
How many times does this object STOP moving?
What is 1s?
Evidence that a new substance formed includes color change, gas, smell or this.
What is light or sound?
This explains why metal is used for cooking pans.
What is a conductor?
This investigation would best show how mass affects motion: rolling a light ball and a heavy ball down the same ramp.
What is an investigation comparing mass and motion?
This data helps infer motion: distance traveled, time, and this third factor.
What is direction?
At 60 seconds, how far had this object traveled?
What is 40m?
What is a good insulator?
