What is gravity?

• A force that repels two bodies away from each other.

• A force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

• A type of energy that causes objects to move in a circular path.

• A phenomenon that only occurs in outer space.

• Gravitational force

• Frictional force

What is a balanced force?

• Forces that are equal in size but opposite in direction, resulting in no change in motion.

• Forces that are unequal in size and direction, causing an object to accelerate.

• Forces that act in the same direction, increasing the speed of an object.

• Forces that are applied at an angle, resulting in rotational motion.

What is the net force when there are multiple forces acting on an object?

• The total force applied in one direction.

• The overall force acting on an object after all the forces are combined.

• The force that is applied by the object itself.

• The force that opposes the motion of the object.

What is an unbalanced force?

• Forces that are equal and opposite, causing no change in motion.

• Forces that are not equal and opposite, causing a change in motion.

• Forces that act in the same direction, increasing the speed of an object.

• Forces that are applied at an angle, resulting in rotational motion.

The tendency of objects to resist a change in motion is called:

• Momentum

• Inertia

• Acceleration

• Friction

What is the formula to calculate net force?

• Net force = total forces acting in one direction + total forces acting in the opposite direction.

• Net force = total forces acting in one direction - total forces acting in the opposite direction.

• Net force = total forces acting in one direction x total forces acting in the opposite direction.

• Net force = total forces acting in one direction / total forces acting in the opposite direction.

What is Newton's Third Law of Motion?

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

• Objects in motion stay in motion unless acted upon by an external force.

• The acceleration of an object is directly proportional to the net force acting on it.

• Energy cannot be created or destroyed, only transformed.
