Force and Motion Review

Front

What does Newton's 2nd law state?

Back

F = m x a (Force equals mass times acceleration)

Front

How do you calculate force?

Back

Force (F) is calculated using the formula F = m x a, where m is mass and a is acceleration.

Front

What is the acceleration of an object with a mass of 4 kg that experiences a force of 100 N?

Back

Acceleration (a) can be calculated using the formula a = F/m. Here, a = 100 N / 4 kg = 25 m/s².

Front

What are action and reaction forces according to Newton's 3rd law?

Back

For every action, there is an equal and opposite reaction. Example: The baseball bat exerts a force on the baseball, and the baseball exerts an equal and opposite force on the bat.

Front

What is the formula to find mass if force and acceleration are known?

Back

Mass (m) can be calculated using the formula m = F/a.

Front

If a car moves to the right with a force of 1 N, what can be inferred about the net force acting on it?

Back

The net force acting on the car is 1 N to the right.

Front

What is inertia?

Back

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

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force is the Newton (N).

Front

What is the relationship between mass and acceleration in Newton's 2nd law?

Back

Mass and acceleration are inversely related; as mass increases, acceleration decreases if the force remains constant.

Front

What happens to the acceleration of an object if the net force acting on it is doubled?

Back

If the net force is doubled, the acceleration of the object will also double, assuming mass remains constant.
