Mass and Gravity
The force of gravity depends on ________________.
Size(Mass) of an object.
What does the moon's gravity affect on Earth?
The moon's gravity affects the ocean tides.
While you’re ice-skating with your friends, you push off from one end of the rink and slide forward. Based on Newton’s first law of motion, what is true?
You will continue to slide across the ice until a force makes you stop or change directions.
What is the relationship between heavy objects and inertia?
Heavy objects have more inertia.
The bigger the object ...
The stronger the force of gravity.
The Moon's gravitational pull is the strongest and is the weakest.
How is velocity different from speed?
Velocity is speed and direction together.
Which has more inertia a couch or a skateboard? Explain
A couch because it is heavier so it has more inertia.
Would a feather have more mass and gravity than a golf ball? Explain.
No, because the ball is bigger so it would have more gravity due to its mass.
Can lakes be affected by the Moon? Yes or No
What does friction do to a moving object?
Slows it down
You are riding in the car with your grandfather, and he turns left. Why do you shift to the right?
It takes you a moment to catch up with the new velocity of the car.
What does mass and weight have in common?
Both can be measured by the same standard units.
The laws of motions.
What does the second part of Newton’s first law say about objects at rest?
They will stay at rest unless an outside force makes them move.
What is the difference between mass and weight?
Mass does not change and weight does based off its location.
The law of inertia is when an object will remain at rest or in motion unless acted on by a force.
Your friend kicks a soccer ball, and it stops a few feet from you. What needs to happen to it in order for it to return to your friend?
Force has to be applied to the ball.
Is inertia and gravity the same? Explain.
No, inertia is a resistance of any physical object in its state of motion, while gravity is the attracting uneven distribution of masses together.
