Front

Forces can change an object's motion by changing its ------, its direction, or both.

Back

speed

Front

Accelerations are produced by ------.

Back

forces.

Front

An object accelerates 5 m/s² when a force of 20 newtons is applied to it. What is the mass of the object?

Back

4 kg

Front

An object with a mass of 5.0 kg accelerates 8.0 m/s² when an unknown force is applied to it. What is the amount of the force?

Back

40 N

Front

The pull of the earth is known as ------.

Back

gravity

Front

Newton's second law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. What is the formula?

Back

F = ma

Front

What does 'net force' refer to in physics?

Back

The total force acting on an object after all the forces are combined.

Front

If an object has a mass of 10 kg and is subjected to a net force of 50 N, what is its acceleration?

Back

5 m/s²

Front

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

Back

Newton (N)

Front

What is the relationship between mass, acceleration, and force according to Newton's second law?

Back

Force equals mass times acceleration (F = ma).
