VOCAB
A push or a pull that causes an object to undergo a change in speed, a change in direction, or a change in shape.
Force
The tendency of objects to resist a change in their state of motion
Inertia
A toy car continues rolling on a smooth surface until it hits a wall and stops.

What is potential energy?
stored energy; energy at rest
Opening your car door
push or pull
A scalar quantity that is defined as the distance traveled per unit of time
Speed
A change in the position of an object over time
Motion
A person needs to apply more force to push a heavy box compared to a lighter box.
second
What is kinetic energy?
energy of motion
An apple falling off a tree
gravity
The difference between the final position and the initial position
Displacement
A tool that is used for measuring the force acting on an object.
Dynamometer
A paper airplane flies further when you throw it harder.
second
A slingshot pulled back
Brakes on a car slowing down the vehicle
friction
The rate at which velocity changes over time
Acceleration
The force of gravity acting on an object
Weight
When a person jumps off a diving board, the diving board pushes them upward into the air.
third
Birthday candles burning
kinetic energy
Picking a flower
pull
A vector quantity that is defined as the speed of an object in a specific direction.
Velocity
When an unequal amount of force is applied to the object, these forces cause a change in motion of an object.
Unbalanced Force
When you blow up a balloon and let it go, the air rushes out one way, and the balloon moves in the opposite direction.
third
What is the definition of work in science?
Whenever a force moves an object in the same direction as the force being applied
