100
The rate in which velocity changes
What is Acceleration
100
In baseball, a fly ball happens when a player hits the ball high into the air. The player on the other team must wait for it to come down to catch it. Imagine that there were suddenly no gravity on Earth. How would a fly ball be different?
What is fly ball would never come down.
100
An unbalanced force acted on the rock and caused it to move.
Why did the rock suddenly begin moving down the side of the hill?
100
Newton
What is a unit of force in the metric system.
100
The moon exerts a smaller gravitational force because it has less mass than Earth.
Why you weigh less on the moon?
200
Only the force of gravity is accelerating it.
What is free fall?
200
What describes the tendency of a moving object to continue moving at the same velocity?
What is inertia?
200
The motion of the object is changing.
What is an unbalanced force is acting on an object?
200
The gravitational force between two objects depends only on their masses. True or False?
What is False.
300
How do we measure Force?
What is Newtons.
300
You are investigating forces, F=friction, F=Force. You try to move a sneaker but it doesn't move.
What is The Friction and the Force have equal strength.
300
Orbiting Earth, you would weigh less than standing on Earth.
What is Distance. (there would be a greater distance between you and the Earth, and gravity is related to distance!)
300
A force where you connect with an object or a person.
What is a Contact Force?
300
A rocket burns fuel to create hot gasses that explode violently out of the rocket engine. This explosion creates thrust. Thrust is a force that pushes the rocket upward. What force must thrust overcome in order to send a rocket into space?
What is gravity?
400
What must two objects have for gravity to exist between them?
What is Mass.
400
Which has the greatest force of gravity acting between them.
What is Two objects with a large mass, close together.
400
The tendency of a moving object to continue moving at the same velocity.
What is a Newton?
400
If you are orbiting Earth, you weigh less than you do standing on Earth. Why would your weight in orbit be lower than your weight on Earth's surface?
What is There would be a greater distance between you and Earth, and gravity is related to distance.
500
The gravitational force between the objects would increase.
What is happen if the mass of one of two objects suddenly increased?
