Motion
A force that opposes motion.
What is a friction?
A force is a ______ or a ________.
What is a push or pull?
Two factors that affect the amount of gravity felt between two objects.
What are: how close together they are and their masses?
The tendency of an object to resist a change in motion.
What is inertia?
If distance increases between two objects, the force of gravity does this.
What is; it decreases?
Name two types of contact forces.
What hitting, kicking, pushing, throwing, etc.?
The combination of all forces acting on an object.
What is a net force?
This is the direction friction acts in relation to the direction the object moves.
What is opposite?
This law, represented by equation F = M x A, states that the acceleration of an object depends on its mass and the net force acting on it.
What is Newton's 2nd Law of Motion?
The greatest velocity a falling object reaches.
What is terminal velocity?
--------------> <---------------------------
Are the above forces balanced?
What is no?
Forces acting on an object that result in a net force and cause a change in the object's motion.
What is an unbalanced force?
This measure changes as the force of gravity changes.
What is weight?
This law states that for every action, there is an equal but opposite reaction.
What is Newton's 3rd Law of Motion?
Since weight is a measure of gravity, it can change with location (Moon versus Earth for example). Mass; however, always does this.
What is stays the same?
These keep an object from changing it motion.
What are balanced forces?
A box is being pushed in opposite directions by two people: 5 N ----> BOX <---- 5N. The net force is this.
What is 0 Newtons?
If mass increases, the force of gravity does this.
What is: it increases?
Newton's 1st Law of Motion states this.
What is: An object at rest will stay at rest and an object in motion will stay in motion unless acted upon by an unbalanced force?
Acceleration of an object is directly related to the _________ and indirectly related to its ________.
What is force applied and mass?
Speeding up, slowing down, or changing direction. What one word describes these?
What is acceleration?
A box is being pushed in opposite directions by two people: 15 N ----> BOX <---- 12N. The net force is this.
What is 3 Newtons ----> ?
Acceleration due to gravity is of this value.
What is 9.8 m/s2
A large horse and a small dog are running at you at the same velocity. The horse, with its greater mass, will be harder to stop because it has greater this.
What is inertia?
What is the weight of a 3 kg rock?
What is 29.4 N?
