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 lose your balance and fall over before you reach the middle of the rink.
You will continue to glide until a force causes you to stop or change direction,
The force of gravity will keep your velocity until your friends make you stop.
The size of your skates will determine how quickly or slowly you move over ice.
How is velocity different from speed?
Velocity is when an object goes in reverse.
Velocity is the direction an object moves in; it has nothing to do with speed.
Velocity is speed and direction together.
Velocity is exactly the same as speed.
What is the relationship between heavy objects and inertia?
Only heavy objects have inertia.
Heavy objects have more inertia.
Heavy objects have less inertia.
Heavy objects have no inertia.
You are riding in the car with your grandfather, and he turns left. Why do you shift to the right?
It takes a moment to catch up with the new velocity of the car.
You have more inertia than the car, so it takes longer for you to shift to the left.
You had been sitting at rest until the force of the turn set you in motion.
The car continued in the same velocity, but you had a different inertia.
What does the second part of Newton’s first law say about objects at rest?
They cannot move unless they have a bit of friction.
If they are heavy, they will stay at rest, but if they are light, they will move.
They will stay at rest unless an outside force makes them move.
They have more inertia than objects in motion.
A force which tries to pull two objects towards each other is
gravity
inertia
mass
speed
Anything with ____________ also has a gravitational pull.
mass
size
depth
light
What is weight?
how much fat is on your body
how strong you are
how strongly your body is being pulled down by gravity
when you have to stand in line
Inertia tells us that we need ____________ to get an object moving or to make it stop.
a force
gravity
friction
strength
Why do the planets in our solar system orbit the sun?
because the sun is the brightest object
because the sun was there first
because the sun has the most mass
because nothing can orbit planets
What keeps the planets in orbit around the sun?
gravity and inertia together
gravity
inertia
neither gravity or inertia
What would happen to Earth if there were no inertia?
Earth would crash into the sun
Earth would fly out to space
Earth would collapse
Earth would orbit the moon
What would happen to Earth if there were no gravity?
Earth would crash into the sun
Earth would fly out to space
Earth would collapse
Earth would orbit the moon
If you dropped a bowling ball and a golf ball off the top of a tall building, which one would hit the ground first?
bowling ball
golf ball
they would hit at the same time
they would not hit the ground
