Physics Effects of Forces and vectors

What is newtons 1st law?

An object will travel in a straight line at constant velocity unless a net force acts

What is newtons 2nd law?

When a net force acts the acceleration is directly proportional to the force applied and inversely proportional to the mass

What will a resultant force do to an object’s velocity?

Change it’s direction or speed

What is solid friction?

The force between two surfaces that may impede motion or produce heating

How do things moving in a circle work?

The force is directed towards the center which keeps the object from moving in a circle. The velocity at any time is a tangent from the circle. The force and velocity are always perpendicular

What happens in a circular motion when the speed increases?

The force increases

What happens in a circular motion when the radius decreases?

The force increases

What happens in a circular motion when the mass increases?

The force increases

What are some vector quantities?

Force, weight, velocity, acceleration, electrical and gravitational field strength and momentum

What are some scalar quantities?

Distance, speed, time, mass, energy and temperature
