What is an object shot through the air.
What is a projectile?
How far the object goes is called?
Range
The path a planet takes is called its
Orbit
Centripetal Force points to the...
center of path of motion
Centripetal acceleration points to . . .
the center of the path
What is the path a projectile takes called?
What is the trajectory?
A projectile is shot at 20 degrees. What other angle would give you the same distance.
70 degrees
A Planet rotating on its axis is called
Rotation
Objects that have circular motion move in a ....
Circular Path
Centripetal acceleration is caused by changing . . .
direction
Horizontal motion remains . . .
Constant
Vertical motion changes due to . . .
gravity
What causes the Earth to have seasons?
Earth's Tilt
Two cars go around a curve. If one is moving twice as fast, which car would be more likely to go off the road? Why is this the case?
The faster one since it needs more force to stay on the road
Angular momentum is the tendency for an object moving in a circular way (rotating) to ...
continue in the same way
Why does a 45 degree angle give you the maximum distance?
The vertical and horizontal velocities are balanced
Why does a high angle cause a projectile to hit early?
IT goes too much up and not enough out
Does Jupiter move faster or slower than the Earth, How do you know?
Slower, because it is farther away from the sun
An ice skater is spinning in a circle with her arms out. What would you expect to happen to her speed if she brought her arms in. Why is this the case?
She speeds up because her radius is smaller
If you wanted to design a curve that allows cars to go around at high speeds.
Make a wide curve
If you want a projectile to go farther than it is currently launching, what is one thing you can do to the launcher to make it go further?
Increase angle or velocity
To make a projectile go higher, what is one thing you can change about the projectile or the launcher?
Launch it directly up
Does Mercury have a longer or shorter period of revolution than Earth, Why?
Shorter because it is closer to the sun
You are spinning a ball on a string around you when the string suddenly snaps. In what direction would the ball go and why? Draw a picture to help explain it if it helps.
In the direction it was going
How would you remove a satellite from the Earth's Orbit?
Slowing it down
