1st Law
Newton’s First Law is also known as:
Law of Inertia
Newton’s Second Law states that acceleration depends on:
Net Force and Mass
Newton’s Third Law states that for every action, there is a(n):
Equal and Opposite Reaction
Speed is the change in __________ over a specific amount of _________.
Distance; Time
Acceleration is the change in __________ or __________ over time.
Speed; Direction
An object at rest tends to stay at rest unless acted on by a(n):
Unbalanced Force
The formula for Newton’s Second Law is:
Force = Mass × Acceleration
An example of Newton’s Third Law is:
A rocket taking off
The formula for speed is:
Distance ÷ Time
The formula for acceleration is:
Speed ÷ Time
The tendency of an object to resist a change in motion is called:
Inertia
If the same force is applied to two objects of different masses, the object with less mass will:
Accelerate More
Newton’s Third Law explains that forces always act in:
Equal and opposite pairs
Velocity is __________ in a given __________.
Speed; Direction
If an object’s velocity changes, it is experiencing:
Acceleration
If an object is at rest, what can you infer about the forces acting on it?
They are balanced
More force means more ________.
Acceleration
When tectonic plates are under tension, they can create:
Earthquakes and Volcanoes
On a distance-time graph, a straight diagonal line represents:
Constant Speed
What type of force is needed to change the motion of an object?
Unbalanced Force
If a moving object has no unbalanced forces acting on it, it will:
Continue moving at the same speed in the same direction
The unit used to measure force is:
Newtons (N)
If an object is accelerating, what must be happening?
An unbalanced force is acting on it
A steeper line on a speed graph means:
Greater Speed
If you increase the mass of an object while applying the same force, what happens?
The object’s acceleration decreases
