What is the definition of force?

• Force is the speed of an object

• Force is the color of an object

• Force is the temperature of an object

• Force is a push or pull upon an object resulting from the object's interaction with another object.

What is frictional force and give an example of it?

• Example: When a car's tires grip the road to slow down or stop the car, frictional force is at work.

• Example: When a magnet attracts metal, frictional force is at work.

• Example: When a ball rolls down a hill, frictional force is at work.

• Example: When a plane takes off, frictional force is at work.

What are the units of measurement for force?

• Kilograms

• Meters

• Liters

• Newtons

How does the direction of force affect an object's motion?

• The direction of force has no effect on an object's motion

• The direction of force only affects the speed of an object

• The direction of force causes the object to shrink or expand

• The direction of force affects an object's motion by causing it to accelerate, decelerate, change direction, or remain at rest.

Explain the difference between balanced and unbalanced forces.

• Balanced forces cause an increase in speed, while unbalanced forces cause a decrease in speed.

• Balanced forces result in no change in motion, while unbalanced forces cause a change in motion.

• Balanced forces result in an object at rest, while unbalanced forces result in an object in motion.

• Balanced forces result in a change in motion, while unbalanced forces cause no change in motion.

• Force has no effect on the motion of an object

• Force only affects the color of an object

• Force can make an object disappear

• Force can change the speed, direction, or shape of an object's motion.
