A _____ is required to change the velocity of an object
Force

Truck B will
What is Newton's First law?
Newton's first law is that anything not moving will continue to not move and anything moving will continue to move. This is also known as the law of inertia.
Define Velocity
A push or pull that can change the motion of an object
A stronger force exerted on an object does what?
A greater change in energy
Two apples are dropped from the same roof. Which will hit the ground first?
They will hit the ground at the same time
Define Friction
A force between an object and the surface it is moving over
A small change of velocity means that ____
A small force was exerted on that object
Truck A is going down a ramp at 80mph weighing 1000 pounds. Truck B is going down a ramp at 70 mph weighing 900 pounds. Which will get to the bottom first?
What is Newton's third law?
For every action, there is an equal and opposite reaction.
Define cause
An event or process that leads to a result or change
When an object changes velocity what happens?
A force is exerted on that object
What is an example of inertia?
(Answers may vary) I leave a banana on the table, it won't move unless effected by an outside force
What is Newton's Second law?
Force = mass times accelerations
Define Effect
A result or chance that happens because of an event or process.
How can an object change velocity?
It depends on the amount of force exerted on that object
Object A has a mass of 10 and an acceleration of 10
Object B has a mass of 9 and an acceleration of 11
Which object will go faster?
Object A
