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 does it mean if forces are balanced?

Back

Balanced forces occur when two forces acting in opposite directions on an object are equal in size, resulting in no change in motion.

Front

What is an example of unbalanced forces?

Back

A bowling ball knocking over pins is an example of unbalanced forces, as the ball exerts a greater force than the resistance of the pins.

Front

Define Inertia.

Back

Inertia is the tendency of an object to resist a change in its motion.

Front

According to Newton's second Law, what affects the amount of force needed to change an object's motion?

Back

The mass of the object and the acceleration required to change its motion.

Front

What is the relationship between mass and force in Newton's second Law?

Back

The greater the mass of an object, the more force is required to accelerate it.

Front

True or False: Acceleration only occurs when an object speeds up.

Back

False. Acceleration can also occur when an object slows down or changes direction.

Front

What is the formula for calculating force?

Back

Force (F) = Mass (m) x Acceleration (a)
