What is a force?
A push or a pull on an object.
What is an unbalanced force?
When the net force acting on an object is not 0N, the forces are unbalanced forces.
What is Newton's first law of motion?
Newton's first law of motion states that if the net force acting on an object is zero, the motion of the object does not change.
What is Newton's second law?
Newton's second law of motion is acceleration, mass, and force.
What is Newton's third law?
For every action there is a reaction.
(Action-Reaction)
What is a contact force?
A push or a pull applied from one object to another.
What is a balanced force?
A balanced force is when the net force on an object is zero newtons, the forces acting on the object are balanced.
What is inertia?
Inertia is the tendency of an object to resist a change in motion.
What is acceleration?
What is a force pair?
A force pair is when two objects exert forces on each other, the two forces are a force pair.
What is a non-contact force?
A push or a pull applied by one object to another object that is not touching it.
What are the three forces of a contact force?
Applied force, Elastic force, and Normal force.
What is constant speed?
An object moving at the same speed for a same period of time.
Friction
What is an action force?
When two objects apply forces on eachother, one of the forces is called an action force, and the other is called the reaction force. (Action-Reaction)
What is friction?
Friction is a contact force that resists the sliding motion between two objects that are touching.
What are the three noncontact forces?
Electric force, Magnetic force, and Gravity.
What is velocity?
Velocity is speed in a given time.
A 24N net force acts on an 8kg rock, what is the acceleration of the rock?
24N/8KG=3
What is action-reaction?
For every action, there is an equal and opposite reaction.
-150N
The force decreases
If one force on an object is 5N upward and the other force is 10N downward, what is the objects motion?
5N Downward.
What is the mathematical equation for Newton's second law of motion? -Albert
Acceleration = Net force/mass
If the force of the man's head on the ball is 1.5N upwards, what is the force of the ball on the man's head?
It would be 1.5N downwards.
