What is this graph showing?

• Constant Speed

• Acceleration (speeding up)

• Deceleration (slowing down)

• No motion

An object at rest will remain at rest or in the same uniform motion unless acted upon by an unbalanced force: law of inertia.

• Newton's First Law of Motion

• Newton's Second Law of Motion

• Newton's Third Law of Motion

as mass increases, the acceleration has to decrease: the law of acceleration

• Newton's First Law of Motion

• Newton's Second Law of Motion

• Newton's Third Law of Motion

If one object exerts a force on a second object, the second object exerts a force equal in magnitude and opposite in direction on the object body; law of interaction

• Newton's First Law of Motion

• Newton's Second Law of Motion

• Newton's Third Law of Motion

How is gravity affected by mass?

• the larger the mass of the object, the greater the gravity

• small objects have no gravity

• gravity is not affected by mass of objects, whether large or small

A ball is moving in a certain direction.  What would happen to the ball if a greater force was applied on the ball along its direction of motion?

• The speed of the ball would decrease.

• The speed of the ball would increase.

• The ball will stop instantly.

• The ball will change direction.
