? = mass x acceleration
or
? = m x a
is used to find
What force is acting on the cat at the end?
Gravity
Friction
Momentum
A 10 kg, 15 kg, and 20 kg rock are rolling down a hill. Which rock will require the most force to stop?
10 kg rock
15 kg rock
20 kg rock
All 3 rocks will require the same force
What does Newton's Third Law state?
For every action there is an equal and opposite reaction.
When masses are the same, the exert the same amount of force.
An object will not move unless acted on by an unbalanced force.
F = m x a
In which direction would this object move and by how much?
10 newtons to the left
10 newtons to the right.
5 newtons to the right
The object would not move
Which dog would be easier to pick up?
The larger dog due to the larger mass.
The smaller dog due to the smaller mass.
Smaller mass = less inertia
The larger dog because it takes up more space.
Neither. You would exert the same amount of energy picking up both dogs.
When are forces considered to be unbalanced?
Forces are always balanced
Forces are considered to be unbalanced when the net force acting on the object is greater than zero.
When the net force is zero
When friction is applied.
What is inertia?
An object’s tendency to resist a change in motion.
The friction that acts on an object after it is in motion.
An object that has an equal reaction force.
A force pair
Which activity would BEST demonstrate the Law of Action/Reaction?
A car traveling down the road.
A rocket launching to space.
A soccer ball sitting on the ground.
A lady pushing a grocery cart.
Which activity would BEST demonstrate Newton's law of Inertia?
A plate sits on a table top.
A lady pushes a grocery cart.
A child jumps on a trampoline.
A boy swings a baseball bat.
Which activity would BEST demonstrate the Law of Force and Acceleration?
A lady pushes a grocery cart.
A boy swings a baseball bat.
A soccer ball sits on the ground.
A rocket launches into space.

How would the moon appear from point B?
True or False? The Sun has a greater influence on Earth's tides than the moon.
False
True
Tides are caused by _________________
the gravitational pull of the moon only.

the action of Earth's tectonic plates.
the combined gravitational forces of the sun and moon.
What happens during a solar eclipse?
The sun blocks the moon from Earth.
The moon blocks the light from the sun from Earth.
The Earth blocks the moon from the sun.
The Earth blocks the light from the sun on the moon.
Lunar eclipses last for a longer period of time.
