AKS 8a-c Forces & Motion Review

Front

What is net force?

Back

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

Front

If an object has 8 N of force to the left and 4 N to the right, what is the net force?

Back

4 N to the left.

Front

What does it mean for forces to be balanced?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be caused by a change in speed or direction.

Front

According to Newton's first law of motion, what happens to a moving object if no unbalanced forces act on it?

Back

It will remain in motion.

Front

What does a flat line on a distance-time graph indicate?

Back

The object is not moving.

Front

What is the relationship between mass and acceleration?

Back

According to Newton's second law, acceleration is inversely proportional to mass when the same force is applied.

Front

What is the formula for calculating force?

Back

Force = mass × acceleration (F = ma).

Front

What is inertia?

Back

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

Front

What happens to an object's motion when it experiences an unbalanced force?

Back

The object will accelerate in the direction of the unbalanced force.
