Force and Motion EOG Review 1

Which will slow an object in motion?

• speed

• friction

• gravity

• momentum

Some clocks keep time by using a weight to move the clock hand around the clock face. The weight is attached by a rope. The weight moves down a small amount as each minute passes. What force moves the weight down so the clock hand shows the right time?

• buoyancy

• friction

• gravity

• magnetism
