Motion and Forces Concepts

Front

What is acceleration?

Back

The rate at which the speed (speed up or slow down) or direction of motion of an object changes over time.

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.

Front

In a tug of war, if Team A pulls with 25N and Team B pulls with 35N, who wins?

Back

Team B wins by 10 N.

Front

What force works against motion?

Back

Friction.

Front

What is the difference between speed and velocity?

Back

Speed is how fast an object is moving, while velocity includes both speed and direction.

Front

What is net force?

Back

The total force acting on an object, taking into account both magnitude and direction.

Front

What happens to an object at rest when balanced forces act on it?

Back

It remains at rest.

Front

What happens to an object in motion when unbalanced forces act on it?

Back

It accelerates in the direction of the net force.

Front

If a car is traveling at 60 mph, what is its speed?

Back

60 mph.

Front

If a car is traveling at 60 mph to the north, what is its velocity?

Back
