Forces Quiz

What is an unbalanced force?

• A force that does not cause any change in an object's motion or shape.

• A force that only affects the shape of an object but not its motion.

• A force that causes a change in an object's motion or shape.

• A force that is always balanced and does not cause any change in an object's motion or shape.

What is a balanced force?

• A balanced force is a force that is smaller in magnitude than another force, resulting in an object's motion slowing down.

• A balanced force is a force that is applied at an angle to another force, resulting in an object's motion changing direction.

• A balanced force is a force that is equal in magnitude and opposite in direction to another force, resulting in no change in an object's motion.

• A balanced force is a force that is greater in magnitude than another force, resulting in an object's motion speeding up.

Define forces.

• Interactions between objects that cause changes in taste or smell.

• Interactions between objects that cause changes in size or color.

• Interactions between objects that cause changes in motion or shape.

• Interactions between objects that cause changes in temperature or pressure.

What are the types of friction?

• surface friction

• static friction, kinetic friction, and rolling friction

• fluid friction

• air friction

Explain static friction.

• Static friction is the force that causes two surfaces to slide past each other when they are in contact and at rest relative to each other.

• Static friction is the force that occurs between two surfaces when they are in motion relative to each other.

• Static friction is the force that prevents two surfaces from sliding past each other when they are in contact and at rest relative to each other.

• Static friction is the force that occurs between two surfaces when they are not in contact with each other.

Explain kinetic friction.

• The force that opposes the motion of an object through a fluid.

• The force that attracts two objects towards each other.

• The force that opposes the relative motion between two surfaces in contact when they are sliding against each other.

• The force that causes an object to move in a circular path.

What is rolling friction?

• Resistance encountered by an object when it is lifted off a surface.

• Resistance encountered by an object when it slides over a surface.

• Resistance encountered by an object when it rolls over a surface

• Resistance encountered by an object when it is submerged in a liquid.

What is fluid friction?

• Resistance that occurs when an object moves through a fluid

• The force that occurs when an object moves through a gas.

• The force that opposes the motion of an object in a vacuum.

• Resistance that occurs when an object moves through a solid.

How do you calculate weight?

• mass * acceleration due to gravity

• mass - acceleration due to gravity

• mass + acceleration due to gravity

• mass / acceleration due to gravity

What is the formula for weight calculation?

• weight = mass / acceleration due to gravity.

• weight = mass + acceleration due to gravity.

• weight = mass - acceleration due to gravity.

• weight = mass * acceleration due to gravity
