Motion
What is the term for a change in an object’s position relative to a reference point?
Motion
Which visual represents a quantity that has both magnitude and direction?
A vector
Which is the force that states that an object can apply to another object without touching it?
Non-contact force
What is the kind of force that resists the sliding motion between two surfaces that are touching?
Friction
Which form of energy is due to motion?
Kinetic energy
What is the name for the starting point you choose to describe the location or position of an object?
reference point
What is the term for the measure of change in velocity during a period of time?
Acceleration
Which force is a kind of force that occurs when one object collides with another object, and another force is applied to the second object?
Collision force
What is the name for the attractive force that exists between all objects that have mass?
Gravity
Which kind of energy is due to interactions between objects or particles when distance changes?
Potential energy
What is the name for an object’s distance and direction from a reference point?
It's position
What is a model that helps to understand systems of objects with any amount of applied forces?
Free-body diagram
What is the term for when the forces of two objects apply to each other?
Force pairs
The law that has an equation that states that the acceleration of an object equals the net force on the object divided by the object’s mass?
2nd law of motion
What is the name for when we calculate a moving object's speed and direction?
Velocity
What is the term for the measure of the distance an object travels in a given amount of time?
Speed
Which visual is a model that shows an object's position at regular, equal time intervals?
Motion diagram/graph
Which is a kind of force that pushes perpendicular to the object’s surface?
Normal force
Which law states that an object in motion will stay in motion, and an object at rest will stay at rest unless acted on by a force?
1st law of motion
Which form of energy is stored in objects that are compressed or stretched?
Elastic potential energy
What is the name for the difference between an object’s initial position and its final position?
Displacement
Which is a visual that representa when you find the sum of all the forces acting on an object, taking into account opposing forces?
Net force
Which is a kind of collision that occurs when colliding objects bounce off each other?
Elastic collision
Which law states that when an object applies a force upon another, the second object applies a force of the same strength on the first object, but the force is in the opposite direction. For every force there is an opposite equal force.
3rd law of motion
What is the invisible force of attraction that draws any two objects with mass toward each other?
Gravitational force/pull
