Energy
What form of energy is sound?
Mechanical
What is the strongest force?
Strong Nuclear
In a free fall, what do we know about the acceleration?
It is constant
How would your mass vs. weight differ if you were to travel to a different planet?
mass would remain the same and weight would change due to gravity
What form of energy is light?
Electromagnetic
What do you know about the direction of the force of friction in comparison to the movement of an object?
It is always the opposite
In a free fall, what happens to the velocity of an object?
It increases because it is accelerating.
What is the rate at which work is done?
Power
What has the same unit of measurement as Energy and what is the unit?
Work; Joules
Name all 3 laws of motion in order.
You can use the shortened versions.
1. Inertia
2. F=ma
3. Action-Reaction
the slope
What is the ability to do work?
Energy
What characteristic determines the amount of gravitational potential energy an object has?
the height
What do we know is true about the forces acting on an object if it is moving at a constant speed?
Net force is zero Newtons (they are balanced)
A student writes, “A bird that is diving for prey has a speed of -10 m/s .” What is wrong with the student's statement? What has the student actually described?
-The speed is a scalar which does not include direction so it should not be negative.
- Velocity

As an object is moved up and down, what happens to the total amount of energy?
It remains the same.
What is the key element in how to slow down an object's momentum and reduce the impact felt by the object/person?
Increasing the time over which the force is applied
A person shoots a basketball into the hoop.
If you were to follow the position of the basketball along the path it took, what would the velocity be at its peak?
0
position is another way of saying displacement and velocity would be your slope.
What characteristic directly relates to the amount of inertia an object has?
mass
