25 Newtons
20 Newtons
200 Newtons
10 Newtons

3.5 kilogram
350 kilograms
0.35 kilograms
35 kilograms
How does inertia change as mass increases?
Inertia would increase
Inertia would Decrease
Mass has no effect on inertia
It would depend on the acceleration
This car is turning, but there’s a puddle of water in the road. Which diagram best shows how the puddle will affect the path of the car after it hits the puddle?
What is the centripetal force acting on a satellite orbiting the Earth?
Tension
Inertia
Gravity
Acceleration
Why do astronauts appear to be weightless in space?
They are weightless, no gravity in space
They are in a state of constant free-fall
They aren't totally weightless, just in micro-gravity
Space is made up by NASA, so astronauts are just in a gravity blocking bunker
The Net Force acting on an object is proportional to both the mass and the resultant acceleration of that object. (F = m x a)
Newton's First
Newton's Second
Newton's Third
Newton's Universal Gravity

The feather will hit the ground first
The bowling ball will hit the ground first
They will hit the ground at the same time
They will both float in the air
When a force is exerted on an object, an equal and opposite force is exerted by the object. These forces are referred to as ______________?

Frictional Forces
Gravitational Forces
Action-Reaction Forces

149.5 m/s2
3,000 m/s2
7,500 m/s2
If the rocket has a mass of 5 kg, the gasses have a mass of 0.5 kg and there is 1,500 N of force being exerted, what is the acceleration of the rocket?
750 m/s2

If the rocket has a mass of 5 kg, the gasses have a mass of 0.5 kg and there is 1,500 N of force being exerted, why does the rocket accelerate less?
The fins slow it down
The gasses have significantly less mass
Because its the action force not the reaction force
The gasses are assisted by gravity

The galaxy is moving away from Earth.
The galaxy is very hot and has not cooled down yet.
The remnants of an explosion are between the galaxy and Earth.
Cosmic Microwave Background Radiation (CMBR) is the term used to describe the residual microwave radiation observed everywhere in the universe that seems to have no single source. The observation of CMBR is used as evidence of The Big Bang Theory because it is believed to be -
