Force and Motion Review

Front

What is net force?

Back

Net force is the total force acting on an object after all the individual forces are combined. It determines the object's acceleration.

Front

What happens to your body when a car stops suddenly?

Back

Your body tends to keep moving forward due to inertia.

Front

How does mass affect gravity?

Back

Less mass equals less gravitational force.

Front

What is the formula for momentum?

Back

Momentum (p) is calculated as p = mass (m) x velocity (v).

Front

If a car has a momentum of 500 kg m/s and a mass of 50 kg, what is its speed?

Back

The speed of the car is 10 m/s.

Front

What is Newton's Second Law of Motion?

Back

Newton's Second Law states that Force (F) equals mass (m) times acceleration (a), or F = m x a.

Front

How do you calculate force using mass and acceleration?

Back

Force is calculated by multiplying mass by acceleration (F = m x a).

Front

What is inertia?

Back

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

Front

What is the relationship between force and acceleration?

Back

The greater the force applied to an object, the greater the acceleration it will experience.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).
