What is direction (or vectors)?
The acceleration of an object towards Earth (gravity).
What is 9.8 m/s2?
The Force applied to move an object subtracted by the Force resisting the movement (like Friction).
What is Net Force?
The Law that says for every action there is an equal and opposite reaction.
What is Newtons third Law?
The force of gravity acting on an object’s mass.
What is weight?
The speed you read on a speedometer.
What is instantaneous speed?
For acceleration to occur what must be applied to the object?
What is Force?
The Net Force of an object when two equal but opposing forces are applied to it.
What is zero?
The Law of Inertia.
What is Newton’s First Law?

Ela's average speed when she ran a 10K (Km) race in 34 minutes.
What is 0.29 Km/min?

What is 0.2 m/s2?
The size of the gravitational force between two objects depends these two things.
What is the mass of each object and the distance between them?
The Law that states an increase in Force will increase in acceleration and an increase in mass will reduce aceleration.
What is Newton’s Second Law?
The force that acts on an object traveling in a circular path.
What is centripetal force?
