Forces practice test questions

Front

What is required to change the motion of an object?

Back

A net force is required to change the motion of an object.

Front

How do you calculate net force when two forces are acting in opposite directions?

Back

Net force = Force in one direction - Force in the opposite direction.

Front

Which object has the greatest inertia?

Back

A stationary elephant has the greatest inertia because it has more mass compared to the other options.

Front

Why do we experience stronger gravitational attraction with Earth than with the Sun?

Back

We are closer to the center of the Earth, which results in a stronger gravitational pull.

Front

What happens to the acceleration of Block A if the coefficient of friction decreases?

Back

The lower the coefficient of friction, the greater the acceleration of Block A.

Front

If the weight of Block B is greater than the frictional force on Block A, what happens?

Back

Block A accelerates to the left.

Front

How does the weight of Block B affect the acceleration of Block A?

Back

The greater the weight of Block B, the greater the acceleration of Block 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 mass and gravitational force?

Back

The greater the mass of an object, the greater the gravitational force it exerts.

Front

What is the formula for calculating gravitational force?

Back

Gravitational force (F) = G * (m1 * m2) / r^2, where G is the gravitational constant, m1 and m2 are the masses, and r is the distance between their centers.
