Vocabulary
A push or pull that can change the motion of an object.
What is force?
Balanced forces.
When forces acting on an object are equal.
Can not be created or destroyed
What is energy?
Force
Mass(kg)x Acceleration(m/s^2)
The change in an object's position with respect to time; when something is moving.
What is motion?
When forces acting on an object are unequal. There is a net force in one direction, so the object moves.
What is an unbalanced force?
Energy of motion
What is kinetic energy?
Gravitational potential energy
Mass(kg)x Gravity(9.8 Newtons)x Height(meters)
Newton's third law of motion.
For every action, there is an equal and opposite reaction.
A push or pull acting in one direction that is countered by a push or pull acting in the opposite direction.
What are action/reaction forces?
Energy of heat.
What is thermal energy.
Kinetic energy
0.5 Mass(kg)xVelocity(m/s)^2
Note: Kinetic energy is measured in Joules
Newton's first law of motion
An object in motion will stay in motion, and an object at rest will stay at rest, unless acted upon by an outside force.
A push or pull that requires contact to occur. This force has action and reaction pairs.
What is a contact force?
Stored energy.
What is Potential energy?
Momentum
Mass(kg)x Velocity(m/s)
Newton's second law of motion
The more force applied to an object, the faster it will accelerate, and the more mass an object has, the more force you will need to use to accelerate it.
Any push or pull that doesn't require touching, like gravity.
What is a at-a-distance force?
