Units
This unit is used to measure how long something is, like the length of a pencil
What is a centimeter?
This type of energy is stored in an object because of its position or height above the ground
What is gravitational potential energy?
This type of energy depends on an objects mass and he square of its velocity
What is kinetic energy?
This quantity describes how quickly an object’s velocity changes over time.
What is acceleration?
This occurs when the forces acting on an object are not equal and do not cancel out.
What is an unbalanced force?
You would use this unit to measure how heavy a backpack is
What is a kilogram?
A stretched rubber band has potential energy because of its property
what is its elasticity?
If an object doubles its speed this quantity related to motion increases by a factor of four
What is kinetic energy ?
The SI unit for acceleration, equivalent to meters per second per second.
What is meters per second squared (m/s²)?
When forces are unbalanced, an object will experience this change in motion.
What is acceleration?
This unit measures how much liquid is in a bottle of water
What is a liter?
The higher an object is lifted the more this kind of energy it has
What is potential energy?
The variable in the kinetic energy equation that has the greatest effect on the final value
What is velocity?
An object moving at constant speed in a straight line has this value for acceleration.
What is zero?
A soccer ball that is kicked and begins to move is experiencing this type of force situation.
What are unbalanced forces?
There are 60 of these units in one hour
What are minutes?
this formula is used to calculate gravitational potential energy near Earth's surface: mass x gravity x
What is height?
This physical quantity must be squared when calculating kinetic energy
What is speed?
Increasing speed, decreasing speed, or changing direction all result in this physical quantity.
What is acceleration?
This law explains why unbalanced forces cause an object to accelerate.
What is Newton’s Second Law of Motion?
This unit is best for measuring the distance between two cities
What is a kilometer?
A book sitting on a high shelf has potential energy mainly because of this force pulling it downward
What is gravity?
The law stating that energy cannot be created or destroyed only transformed
What is the law of conservation of energy?
According to Newton’s Second Law, acceleration is directly proportional to this quantity.
What is net force?
If unbalanced forces act in the opposite direction of motion, this will happen to the object’s speed.
What is it will slow down (decelerate)?
