Apply Newton’s First Law to the following illustration.

Laws OF motion

1 “The Law of Inertia” An object at rest tends to stay at rest and an object in motion tends to stay in motion unless acted upon by an unbalanced force.

The direction of the net force is in the same direction as the acceleration. Thus, if the direction of the acceleration is known, then the direction of the net force is also known. Consider the two oil drop diagrams below for an acceleration of a car. From the diagram, determine the direction of the net force that is acting upon the car. Then click the buttons to view the answers.

1.1 To explain forces using Newton’s three laws of motion. Newton’s Second Law

Force equals mass times acceleration. 2 F = ma F = ma Force equals mass times acceleration.

Weight. Every object in the universe with mass attracts every other object with mass. The amount of attraction depends on the size of the masses and how far apart they are. For everyday-sized objects, this gravitational pull is vanishingly small, but the pull between a very large object, like the Earth, and another object, like you, can be easily measured. How? All you have to do is stand on a scale! Scales measure the force of attraction between you and the Earth. Weight is a measure of the force of attraction between you and the Earth (or any other planet) is called your weight. https://www.exploratorium.edu/ronh/weight/

What is the weight of a 75 kg sack of flour on Earth?

What is the weight of a 75 kg sack of flour on Earth?

NEWTON’S SECOND LAW WEIGHT is a measure of the force of GRAVITY on the mass of an object Force is measured in NEWTONS

is the measure of the amount of matter in an object is the measure of the amount of matter in an object. It is measured in GRAMS (g).

ACCELERATION of GRAVITY Force = Mass x Acceleration Force is measured in “Newtons” ACCELERATION of GRAVITY (Earth) = 9.8 m/s2 Weight (force) = mass x gravity (Weight is a measure of the pull of gravity on an object.

Twice as much because the mass is twice as big! F = ma One rock weighs 10 kg. The other rock weighs 5 kg. How much more force will be required to accelerate the first Rock at the same rate as the second rock? F = ma Twice as much because the mass is twice as big!
