What’s the formula for calculating acceleration

S(f)- S(i)/ time

Name Newton’s first law

Anything in motion will stay in motion unless it’s stopped- anything at rest will stay at rest unless it’s moved

Newton’s second law is…

Force= Mass x Acceleration

Newton’s third law is…

For every action there’s an equal and opposite reaction

List some history of Newton…

His job at the royal mince was to find counterfeiters ( people making fake money)

He was born in England 1643

Name is Sir Issac Newton

Name forces or labels you can use for free body diagrams

Applied force- adding force to something, Gravity force- pulling down, Air resistance, frictional force- when pushing something, Normla force- between object and surface

What’s the unit for distance

Meters or m

Unit for time

Seconds or s

Unit for speed?

Meters per second

Unit for acceleration?

Meters per second per second

Units for force?

Newtons or N

Units for mass?

Grams or g

What’s the equation for speed?

Speed = distance / time

Potential energy

This is stored energy. An object has more potential energy the higher up it is

(like a roller coaster at the top of a hill).

Kinetic energy

This is the energy of motion. If an object is moving, it has kinetic energy.

Positive result

The object is speeding up

Negative result

The object is slowing down
