CL.6 BK.2-2-Force and Motion

What is a force?

• A force is a type of energy.

• A force is a fixed quantity that cannot change.

• A force is an interaction that causes a change in motion.

• A force is a measurement of speed.

Name two examples of forces we use daily.

• Magnetism

• Pressure

• Electricity

• Gravity, Friction

What effect does force have on an object's motion?

• Force changes an object's motion by causing acceleration or altering its speed and direction.

• Force makes objects float in the air.

• Force has no effect on motion.

• Force only affects the color of an object.

What is friction?

• Friction is the temperature increase caused by two surfaces rubbing together.

• Friction is the force that enhances the motion of two surfaces in contact.

• Friction is the force that opposes the relative motion of two surfaces in contact.

• Friction is the energy lost when two surfaces slide over each other.

How does friction affect the motion of objects?

• Friction increases the speed of moving objects.

• Friction only acts on stationary objects.

• Friction opposes motion and can slow down or stop moving objects.

• Friction has no effect on the motion of objects.

What happens to friction on a rough surface?

• Friction increases on a rough surface.

• Friction is irrelevant on a rough surface.

• Friction decreases on a rough surface.

• Friction remains constant on a rough surface.

How do shoe treads help prevent slipping?

• Shoe treads are designed to be smooth for better aesthetics.

• Shoe treads are only for decoration and have no functional purpose.

• Shoe treads help prevent slipping by increasing grip through patterns that channel away water and enhance surface contact.

• Shoe treads are made of materials that become slippery when wet.

What is the role of magnetic force in our lives?

• Magnetic force has no impact on modern medicine.

• Magnetic force is primarily a natural phenomenon without practical applications.

• Magnetic force is essential for technology, navigation, and medical applications.

• Magnetic force is only used in toys.

How does gravitational force affect us?

• Gravitational force keeps us grounded, affects our weight, and governs the motion of celestial bodies.

• Gravitational force makes us float in the air.

• Gravitational force only affects objects in space.

• Gravitational force has no effect on our daily lives.

What is electrostatic force?

• The electrostatic force is the force between magnetic objects.

• The electrostatic force is the force that causes objects to float.

• The electrostatic force is the force that only acts on neutral objects.

• The electrostatic force is the force between charged objects.
