This is the amount of matter an body or object contains.
What is mass?
100
In a mechanical interaction between a foot and a soccer ball, this is the energy receiver.
What is the soccer ball?
100
This is the unit of measurement for a force.
What is a newton?
100
This term refers to the force exerted by a planet on an object. It is often confused with mass.
What is weight?
200
Things in an experiment that can be changed or are different.
What is (are) variables?
200
This is the amount of space that something occupies.
What is volume?
200
This is the equation for calculating speed.
What is speed = distance / time?
200
This type of backward force is caused by two things rubbing against each other.
What is friction?
200
These are the two factors that affect the strength of a gravitational interactions.
What is (are) mass and distance between objects?
300
This is something that stays the same during an experiment.
What is a control (or controlled variable)?
300
This is the amount of mass of a standard unit volume. This property also determines whether or not an object will sink or float.
What is density?
300
This is another term for motion energy.
What is kinetic energy?
300
This type of backward force results from resistance when moving through air or liquid. Skydivers depend greatly on this type of force.
What is drag?
300
This is the energy of an object that is dependant on its position.
What is potential energy?
400
If Bob conducts an experiment to determine how different running shoes affect his time in a 40 yard race, the manipulated variable would be this.....
What is (are) the shoes?
400
The volume of a liquid is usually measured in this scientific instrument.
What is a graduated cylinder?
400
This is the average speed of someone who drives 300km in 5 hours.
What is 60 km/hr?
400
If a moving object is experiencing balanced forces, its speed will be...
(increasing, decreasing, or constant)
What is constant?
400
This term refers to the constant speed that a falling object reaches when its downward force of gravity is equal to its upward force of gravity.
What is terminal speed?
500
This is the term for an experiment in which only the manipulated and responding variables are allowed to change and all other variables and conditions are kept the same.
What is a fair test?
500
After adding air to a soccer ball, the mass will do this....
(increase, decrease, or stay the same)
What is increase?
500
This is the term for a change in velocity per unit time.
What is acceleration?
500
An object experiences a constant force of 2N to the right. The object's speed can be described as...
(increasing, decreasing, or constant)
What is increasing?
500
This upward force exerted by a liquid balances the gravitaional force when an object floats.
