Movin' On Up
This is the change in an object's position.
Motion
This is a push or pull.
Force.
This is an object's tendency to stay at rest if it is at rest, or its tendency to keep moving if it is moving.
Inertia
This is the ability to do work.
Energy
This is when the air slows an object down.
Air Resistance
This how fast an object’s position changes over time at any given moment.
Speed
Greater forces can increase this.
Acceleration
Name two things gravity depends on.
The mass of an object, and the distance between objects.
This is energy that is stored up and can be used later.
Potential energy.
This is a force that occurs when one object touches another.
Contact force.
This is the speed and direction of an object.
Velocity
Force often occurs when this happens.
This is a force between surfaces that slows objects or stops them from moving.
Friction
An object has this energy because it is moving.
Kinetic
This is a force that occurs without objects touching.
Non contact force.
This is a change in velocity over time.
Acceleration
This is a force that acts on an object without changing its motion.
Balanced force.
What planet in the solar system has the strongest gravity and why?
Jupiter, because larger objects have more gravity.
The quarterback is waiting for the football. What kind of energy is this?
Potential
What two things affect acceleration?
The force applied and weight.
What is the difference between speed and velocity?
Speed is how fast an object's position changes, velocity is speed mixed with direction.
This is a force that acts on an object and changes its motion.
Unbalanced force.
Icy roads are dangerous because they lack this.
Friction
Uh-oh. The quarterback got sacked. It wasn't the Eagles, I promise. It was probably a New York team. What kind of energy was that?
Kinetic energy.
What is an example of a noncontact force? Hint: It's the reason pigs can't fly.
