A change in motion caused by an unbalanced
force acting on an object; includes increasing
speed, decreasing speed, or a change in direction
Direction
Acceleration
Force
Mass
Which is NOT an example of Acceleration?
An object speeds up
An object slows down
An object changes direction
An object is in constant motion.
Acceleration is a speeding up, slowing down or a change in direction. Is the following acceleration and if so, which one?
A swimmer has 10 meters left in the race and he is neck-in-neck with his competitor. He has a surge of adrenaline and pulls ahead to win.
Yes, this is acceleration since the swimmer starts to speed up to pull ahead.
Yes, this is acceleration since the swimmer uses the wall to change directions.
No, this is not acceleration since there is no speeding up, slowing down, or change in direction.
True or False: You are standing at the bus stop and not moving at all. Since you are not moving, your acceleration would be 0 (zero). Support with how you know.
True since you are not speeding up, slowing down or changing directions.
True since you are traveling no distance in a certain amount of time.
False since you are speeding up, slowing down and/or changing directions.
False since you were going to get on a moving bus.
An Atom's structure is...
made of protons, neutrons in the nucleus and electrons orbiting the nucleus
neutrons only in the nucleus with protons and electrons in orbital paths
electrons and protons in the nucleus
protons, electrons and neutrons Found in the electron cloud

6 protons and 6 neutrons
12 protons and 12 neutrons
6 protons and 12 neutrons
12 protons and 6 neutrons
Which element has 31 protons and 39 neutrons ?
The protons are
found in the energy levels with electrons
found in the nucleus and are equal to the number of electrons
found in the nucleus and equal the number of electrons plus neutrons
