what is projectile motion and what causes it?

Projectile motion is anything that is being thrown by another object.

Newtons 1st law

(Law of Inertia) an object in motion tends to stay in motion & an object at rest stays at rest unless acted upon by an outside force.


the tendency of an object to resist any change in its motion

Newtons 2nd Law

(Force) when force is applied to an object it is accelerated in the direction of the force. (mass and force are inversely proportional)


the state in which one object's distance from another is changing

How are mass and acceleration related

The acceleration of an object depends on an objects mass because the heavier the object is the harder it is for an object to accelerate.

How are force and acceleration related

Force is the product of mass and acceleration.

Newtons 3rd Law

For every action there is an equal and opposite reaction


the force or speed with which something moves

Momentum= mass(KG) x velocity(m/s)

What is the law of conservation of momentum

The law of conservation of momentum states that an object will keep its momentum unless acted on by an outside force.


the rate at which an object moves

Speed= distance/time or s=d/t


speed in a given direction


the force that opposes the motion of one surface as it moves across another surface


(physics) the force of attraction between all masses in the universe


(physics) the influence that produces a change in a physical quantity

Force (N)= mass(KG) x Acceleration (m/s/s)


(physics) a rate of change of velocity
