What is the definition of FORCE?

• A push or a pull exerted on an object.

• Friction-like force that opposes motion of an object in the air or liquid

• The force that resists the start of sliding motion.

• The tendency of an object to resist change in motion.

What is the definition of CONTACT FORCE?

• Force exerted during contact between objects.

• Friction-like force that opposes motion of an object in the air or liquid

• The force that resists the start of sliding motion.

• A push or a pull on an object

What is the definition of STATIC FRICTION?

• Force exerted during contact between objects.

• Friction-like force that opposes motion of an object in the air or liquid

• The force that resists the start of sliding motion.

• The force that resists the movement of two surfaces that are touching

What is the definition of KINETIC FRICTION?

• Force exerted during contact between objects.

• Friction-like force that opposes motion of an object in the air or liquid

• The force that resists the start of sliding motion.

• The force that resists the movement of two surfaces that are touching

What is the definition of DRAG?

• Force exerted during contact between objects.

• Friction-like force that opposes motion of an object in the air or liquid

• The force that resists the start of sliding motion.

• The force that resists the movement of two surfaces that are touching

What is the definition of FIELD?

• Any region in which an object experiences force at a distance.

• Friction-like force that opposes motion of an object in the air or liquid

• The combination of all of the forces acting on an object.

What is the definition of NET FORCE?

• Forces on an object that produce a net force of 0 N(newtons) – there is no motion.

• Friction-like force that opposes motion of an object in the air or liquid

• The combination of all of the forces acting on an object.

• Forces on an object that do not produce a force of 0 N(newtons) – there is motion.

What is the definition of BALANCED FORCE?

• Forces on an object that produce a net force of 0 N(newtons) – there is no motion.

• Friction-like force that opposes motion of an object in the air or liquid

• The combination of all of the forces acting on an object.

• Forces on an object that do not produce a force of 0 N(newtons) – there is motion.

What is the definition of UNBALANCED FORCE?

• Forces on an object that produce a net force of 0 N(newtons) – there is no motion.

• Friction-like force that opposes motion of an object in the air or liquid

• The combination of all of the forces acting on an object.

• Forces on an object that do not produce a force of 0 N(newtons) – there is motion.

What is Newton's FIRST LAW OF MOTION?

• The acceleration of an object depends on the mass of the object and the amount of force being applied.

• An object stays at rest, an object stays in motion, unless an unbalanced force acts upon it.

• For every action, there is an equal and opposite reaction.
