_________________________ states that ANY two bodies of mass in the UNIVERSE have a gravitational attraction to each other, so if you are far out into outer space and are floating “weightlessly” you and the earth will still have a gravitational pull/attraction to each other. That gravitational force just becomes weaker as distance increases.

Newton’s Universal Law of Gravity

If gravity is an invisible force that pulls any two objects of mass towards each other, why don’t people notice the gravitational attraction toward each other?

The force of gravity between people or any other object ON earth is VERY small compared to the gravitational pull of the earth, so it is not noticed.

The gravitational force between people is too strong to be noticed.

People are too far apart to feel the gravitational attraction.

The gravitational force only works on large objects like planets.

There are two planets orbiting a very massive star. Planet A is closer to the star than Planet B, and has more mass than Planet B. Which planet will have a greater gravitational pull towards the star?

Both have the same gravitational pull

Two boys are rolling down a hill. Jerry is at the bottom of the hill. Ralph is about to roll down, at the top of the hill. Which one has potential energy and which one has kinetic energy?

Jerry has kinetic energy, Ralph has potential energy

Jerry has potential energy, Ralph has kinetic energy

Two objects are being pulled up a hill. One object is a container full of baseballs and the other object is a container full of feathers. What is true about the force needed to make these objects move?

More force is needed to move the container full of baseballs.

More force is needed to move the container full of feathers.

The same force is needed to move both containers.

No force is needed to move either container.

Based on the pattern of the relationship between mass and energy, what is the missing amount of energy when a 10 kg object travels at 4 m/s? What is the pattern?

20 Joules; multiply the x-axis by 2

18 Joules; add the first two x and y together to get the missing number

20 Joules; add the mass of the object by to the y-axis

Based on the pattern, what is the relationship between mass and energy?

When the mass doubles, the energy also doubles.

When the mass doubles, the energy decreases.

Why are safety features such as helmets and pads in sports - and airbags, bumpers and crumple zones in vehicles used? Choose 3

To reduce the risk of injury in a collision

to absorb the force and spread it out

Choose the correct description for Graph #1 (distance and time graph):

Steady (constant) speed, pause (stop), continue at a steady speed

Choose the correct description for Graph #2 (distance and time graph):

Steady (constant) speed, pause (stop), continue at a steady speed

Choose the correct description for Graph #3 (distance and time graph):

Steady (constant) speed, pause (stop), continue at a steady speed

Choose the correct description for Graph #4 (distance/position and time graph):

Steady (constant) speed, pause (stop), continue at a steady speed

Define Newton's 1st Law (Law of Inertia)

An object at rest will stay at rest and an object in motion will stay in motion unless acted on by an unbalanced force.

For every action force, there is an equal and opposite reaction force.

The force needed to change the motion of an object is equal to its mass times its acceleration.

Define Newton's 2nd Law

The force needed to change the motion of an object is equal to its mass times its acceleration.

For every action force, there is an equal and opposite reaction force.

An object at rest will stay at rest and an object in motion will stay in motion unless acted on by an unbalanced force.

Define Newton's 3rd Law

For every action force, there is an equal and opposite reaction force.

An object at rest will stay at rest and an object in motion will stay in motion unless acted on by an unbalanced force.

The force needed to change the motion of an object is equal to its mass times its acceleration.
