Forces and Motion Review

Front

What is net force?

Back

The overall force acting on an object when all the individual forces are combined. It determines the object's motion.

Front

What is the direction of a net force of 7N to the right?

Back

The object will accelerate to the right.

Front

What are balanced forces?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Forces that are not equal and cause a change in motion of an object.

Front

How can you tell if an unbalanced force is acting on an object?

Back

The object is moving or changing its motion.

Front

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

Back

It will start to move in the direction of the net force.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia.

Front

What is the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a).

Front

What is acceleration?

Back

The rate of change of velocity of an object.
