Motion
When you have speed in a given direction.
What is velocity?
This is a push or a pull on an object.
What is force?
It states, that all objects in the universe attract each other through gravitational force.
What is the law of universal gravitation?
Is the ability to do work.
What is energy?
The tendency of matter to resist a change in motion.
What is inertia?
A change in speed, direction, or both.
What is acceleration?
Forces are measured in this unit.
What are Newtons?
This increases as mass increases.
What is Gravitational force?
The energy of motion.
What is kinetic energy?
Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first object.
What is Newton’s third law?
When an object changes position over time in relation to a reference point.
What is motion?
This is determined by combining forces.
What is net force?
Is the amount of matter in an object.
What is Mass?
Energy and work are expressed in this unit.
What are joules (J)?
this is a measure of inertia.
What is mass?
The distance traveled by an object divided by the time the object takes to travel that distance.
What is speed?
________ produce no change in motion.
What are balanced forces?
Is a measure of the gravitational force on an object.
What is weight?
Energy that is stored.
What is potential energy?
The acceleration of an object depends on its mass and on the force exerted on it
What is Newton’s second law?
The background used for comparison to determine if an object is in motion.
What is a frame of reference?
Is always exerted by one object on another object.
What is a force?
It is a force of attraction between objects that is due to their masses.
What is gravity?
This is defined as a force moving a specific distance.
What is work?
Objects at rest will not move unless acted upon by this.
What is an unbalanced force?
