Acceleration and Velocity Concepts

Acceleration

• Is the rate at which velocity changes. Any change in speed or direction.

• Is the force applied to an object to change its speed.

• Is the maximum speed an object can achieve.

• Is the distance covered by an object in a given time.

Velocity

• Defined speed in a given direction.

• A measure of how fast something is moving without regard to direction.

• The total distance traveled divided by the total time taken.

• The rate of change of position of an object.

Newton's Second Law

• An object's acceleration is directly proportional to the magnitude of the net force acting upon the object and inversely proportional to its mass.

• An object's acceleration is independent of the net force acting upon it.

• An object's mass is directly proportional to the acceleration it experiences.

• An object's velocity is directly proportional to the net force acting upon it.

Formula to calculate acceleration

• a = f / m

• a = m / f

• a = f * m

• a = f + m

Force

• Push or Pull

• Friction

• Inertia

• Acceleration

Formula to determine force

• F = ma

• F = mv

• F = m/a

• F = m + a

Newton's 1st Law of Motion

• A body at rest will remain at rest, and a body in motion will remain in motion, unless acted upon by an outside force.

• An object will accelerate in the direction of the net force acting on it.

• For every action, there is an equal and opposite reaction.

• An object in motion will eventually come to a stop without any external force.

Newton's 3rd Law

• For every action there is an equal and opposite reaction.

• Energy cannot be created or destroyed.

• Objects in motion stay in motion unless acted upon by an external force.

• Force equals mass times acceleration.
