What is a force?
100
A contact force in which an object is moved away from the person or object exerting the force
What is a push?
100
Newton's Second Law states that force equals this
What is mass times acceleration?
**The formula is F=ma.
100
A bowling ball, a beach ball, and a basketball are rolled with the same force along a horizontal surface. The ball that will roll the shortest distance is the ...
What is the bowling ball?
**The same force is applied to each ball. The ball with the greatest mass (the bowling ball) will have the least acceleration.
100
The difference between balanced and unbalanced forces
What is balanced forces do not cause a change in motion and unbalanced forces do cause a change in motion?
200
Unequal forces that cause an object's motion to change
What are unbalanced forces?
200
An opposing force caused by two objects touching each other; a contact force that will cause motion to slow or stop
What is friction?
200
Newton's First Law states that an object in motion will ...
What is stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force?
200
The water and soap on a slip-n-slide reduces this force, which makes sliding easier (and less painful!)
What is friction?
200
A soap box race is a race in which the cars competing are unpowered, relying completely upon gravity to move. What type of track is best to use for this type of race?
What is a steep track?
Like this one:
300
The tendency to do nothing or to remain unchanged
What is inertia?
300
A noncontact force that pulls masses toward large objects, such as the Earth or the sun
What is gravity?
300
Newton's Third Law states that for every action (force) there is ...
What is an equal and opposite reaction (force)?
300

d. 40
What is d. 40?
300
The difference between a push and a pull
What is a push forces an object away from oneself and a pull forces an object closer to oneself?
400
The unit used to measure force
What is a Newton?
400
A noncontact force that either pulls opposite ends of a magnet together or pushes like ends of a magnet apart
What is magnetic force?
**Remember, opposites attract!
400

a. the faster the object will accelerate.
b. the slower the object will accelerate.
What is a. the faster the object will accelerate?
400

a. increases.
b. decreases.
What is decreases?
400
By kicking a soccer ball with more force, the ball will go ...
What is farther?
500
A change in speed or direction
What is acceleration?
500
A contact force that brings an object closer to the person or object exerting the force
What is a pull?
500
Newton's First Law states that an object at rest will ...
What is stay at rest, unless acted upon by an unbalanced force?
500

Alex threw a baseball into the air, and he caught 1 second later.
Brad threw a baseball into the air, and he caught it 0.5 second later.
Mia threw a baseball into the air, and she caught it 2 seconds later.
The person who exerted the most force on the baseball is ...
Who is Mia?
**The longer the ball is in the air, the higher it went, therefore the most force was exerted on it.
