100
When an object changes speed or direction
What is Acceleration
100
A push or pull on an object
What is a Force
100
an object at rest stays at rest. An object in motion stays in motion unless acted upon by an unbalanced force.
What is Newtons 1st law
100
the tendency of an object in motion to resist any change in motion
What is Inertia

200
the inertia of an object depends on its _____ .
What is mass
300
Observers notice a change in sound as an object moves past them.
What is the Doppler Effect
300
an airplane moving at a constant speed of 500 m/h in a straight line (accelerating?)
What is no, not changing direction or speed
300
forces are measured in _______.
What is Newtons (N)
300
A 2 kg ball is moving at a constant speed of 4m/s. How muuch net force is required to keep it moving?
What is 0N
300
the (more/less) mass = greater inertia.

What is 4 m/s^2
400
Forces that are equal in size but opposite direction. Net force is always 0. No change in Velocity.
What is a balanced force
400
In newtons second law of motion it states that the acceleration of an object is in the same direction as the ______ _______.
What is the net force

What is Radiation
500
A car slows down from 32m/s to 8m/s in 4s. Calculate the acceleration.
What is -6 m/s^2
500
Forces applied to an object in varying sizes and directions. Cause a change in motion or velocity. Net force is never 0
What is an Unbalanced force
