Force & Motion 5th Grade SOL Flashcard

Front

What is the definition of work in physics?

Back

Work is defined as the force applied to an object times the distance over which that force is applied, and it occurs when an object is moved by that force.

Front

Give an example of work being done.

Back

Pushing a cart through the store is an example of work being done.

Front

What happens to the speed of cars during a collision?

Back

The speed of the cars may change due to the collision.

Front

What force keeps the moon in orbit around the Earth?

Back

Earth's gravity is the force that keeps the moon in orbit around the Earth.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change the motion of an object, while unbalanced forces cause an object to accelerate or change its motion.

Front

If a car is speeding up, what type of force is acting on it?

Back

An unbalanced force is acting on the car if it is speeding up.

Front

What is a force?

Back

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

Front

What is the effect of balanced forces on an object?

Back

Balanced forces result in no change in the object's motion.

Front

What is an example of an unbalanced force?

Back

A car accelerating when the driver presses the gas pedal is an example of an unbalanced force.

Front

How does gravity affect objects in motion?

Back

Gravity pulls objects toward the Earth, affecting their motion and keeping them in orbit.
