Science Force and Motion Review

Front

What is the definition of force in the context of motion?

Back

A force is a push or pull that can cause an object to accelerate, change direction, or change shape.

Front

What is the relationship between force and motion?

Back

All motion begins with a force; without a force, an object will remain at rest or continue moving at a constant velocity.

How does the length of a pendulum affect its motion?

Back

Shortening the length of a pendulum increases its frequency, causing it to swing faster.

Front

What is the formula for calculating speed?

Back

Speed is calculated as distance divided by time (Speed = Distance / Time).

Front

If two objects are in motion, how can we compare their speeds?

Back

We can compare their speeds by measuring the distance each object travels over the same time interval.

Front

What factors can affect the speed of an object?

Back

Factors include the amount of force applied, the mass of the object, and any frictional forces acting on it.

Front

What is a pendulum?

Back

A pendulum is a mass hanging from a fixed point that is free to swing back and forth.

Front

How does gravity affect the motion of a pendulum?

Back

Gravity pulls the pendulum down, causing it to accelerate towards the lowest point of its swing.

Front

What is the period of a pendulum?

Back

The period is the time it takes for the pendulum to complete one full swing back and forth.

Front

How can you estimate the speed of an animal, such as a lion, based on distance?

Back

You can estimate speed by measuring the distance between two points and the time it takes to travel that distance.
