EOG REVIEW: Force & Motion

Front

What is the force that opposes the motion of an object and can cause it to stop?

Back

Friction

Front

Which object requires more force to stop: a 5 kg ball or a 20 kg ball moving at the same speed?

Back

The 20 kg ball requires more force to stop.

Front

What is the relationship between mass and the amount of force needed to change an object's motion?

Back

Greater mass requires more force to change its motion.

Front

What is the term for the rate at which an object covers distance?

Back

Speed

Front

If a force acts on an object in the direction it is moving, what will happen to the object's speed?

Back

The object's speed will increase.

Front

What is the effect of gravity on objects near the Earth's surface?

Back

Gravity pulls objects toward the Earth.

Front

How can you determine if an object is moving faster in one part of a journey compared to another?

Back

By comparing the distance traveled in equal time intervals.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time

Front

What happens to the motion of an object when no net force acts on it?

Back

The object will maintain its state of motion (Newton's First Law).

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.
