Forces Review

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 allows objects to float in space.

• A phenomenon that causes objects to move in a circular path.

What is the formula for calculating force?

• Force = Mass + Acceleration

• Force = Mass / Acceleration

• Force = Mass x Acceleration

• Force = Mass - Acceleration

What is the effect of distance on gravitational force?

• Increasing the distance between two objects decreases the gravitational force between them.

• Increasing the distance between two objects increases the gravitational force between them.

• Distance has no effect on gravitational force.

• Gravitational force is only affected by mass, not distance.

What is an unbalanced force?

• A force that causes an object to change its motion.

• A force that does not affect the motion of an object.

• A force that acts in the opposite direction of motion.

• A force that is equal in magnitude and opposite in direction.

What is inertia?

• The tendency of an object to resist changes in its state of motion.

• The force that causes an object to accelerate.

• The speed of an object in a given direction.

• The mass of an object multiplied by its velocity.

What is the relationship between mass and weight?

• Weight is the gravitational force acting on an object's mass.

• Mass is the amount of space an object occupies.

• Weight is the total amount of matter in an object.

• Mass and weight are the same thing.

What is Newton's 1st Law of Motion?

• Objects at rest or in motion will stay as they are unless acted on by an unbalanced force.

• An object in motion will eventually stop unless a force is applied.

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

• An object will accelerate in the direction of the net force acting on it.

What is the effect of increasing mass on gravitational force?

• Increasing mass decreases the gravitational force between two objects.

• Increasing mass has no effect on gravitational force.

• Increasing mass increases the gravitational force between two objects.

• Increasing mass only affects gravitational force at very large distances.

What is the measure of gravity's pull on an object?

• Mass

• Weight

• Density

• Volume

What is the force of attraction or repulsion between materials made of similar substances?

• Magnetism

• Gravity

• Friction

• Electrostatics
