|
What is acceleration?
|
It is the rate of change of speed or velocity.
|
|
|
What are balanced forces?
|
They are equal forces that act on a single object in opposite directions and cancel each other out.
|
|
|
What is dynamics?
|
It is the study of forces and their effects.
|
|
|
What is a force?
|
It is a push or a pull that can cause a change in the motion of an object.
|
|
|
What is inertia?
|
It is the property of a body that resists any change to its uniform straight motion.
|
|
|
What is net force?
|
It is the overall force on an object after all of the forces acting on it are added together.
|
|
|
What are unbalanced forces?
|
They are unequal forces acting on a single object that don't cancel out and therefore cause a change in the object's motion.
|
|
|
What is the coefficient of friction?
|
It is a number that compares friction force to the force pushing two surfaces together.
|
|
|
What is gravity?
|
It is the natural force of attraction Earth exerts on objects at or near its surface, which tends to draw them toward Earth's center.
|
|
|
What is kinetic friction?
|
It is the frictional force encountered by an object in motion.
|
|
|
What is static friction?
|
It is the force needed to start moving an object at rest.
|
|
|
What is centripetal acceleration?
|
It is acceleration toward the center of a circular path.
|
|
|
What is centripetal force?
|
It is a force acting toward the center of a circular path that makes an object move along that path.
|
|
|
What does 'parabolic' mean?
|
It means 'taking the curves shape of a parabola, which is the path a projectile takes when moving through the air.'
|
|
|
What is the Universal Law of Gravitation?
|
It is, 'There's a gravitational force of attraction acting on any two objects with mass.'
|
|
|
What is uniform circular motion?
|
It is motion at a constant speed in a circular path.
|
|
|
What is buoyancy?
|
It is the upward force exerted on an object in a fluid.
|
|
|
What is density?
|
It is a measure of how much matter there is in a given space. Formally, it's defined as mass divided by volume.
|
|
|
What is a fluid?
|
It is a substance that is able to take the shape of the container that holds it.
|
|
|
What is fluid displacement?
|
It occurs when an object placed into a fluid moves some of that fluid aside to make room for itself.
|
|
|
What is pressure?
|
It is the amount of force being exerted per unit of area.
|
|
|
What is uniform circular motion?
|
It is motion at a constant speed in a circular path.
