If the net force on an object is zero, what can you conclude?

• The object is not accelerating.

• The object is not touching anything.

• The object is not moving.

• The object is slowing down.

• 
• 
• 
• 

What can you infer about an moving object?

• No forces are acting on it.

• Gravity is exerting the strongest force on it.

• The forces acting on it are in balance.

• The forces acting on it are unbalanced.

Acceleration occurs when an object is subjected to a(n)

• force.

• balanced force.

• unbalanced force.

• contact force.

What is true of non-contact forces?

• They are always stronger than contact forces.

• They always drive two objects farther apart.

• They become weaker with distance.

• They can not make two objects touch.

Which of the following statements is always true?

• An object at rest has no forces acting on it.

• Unbalanced forces lead to a change in speed or direction.

• Gravity always leads to an unbalanced force.

• The net force on a moving object can never be zero.

Speeding up, slowing down or changing directions is called

• velocity.

• speed.

• acceleration.
