Force and Motion Test Review

Front

What is the formula to calculate force?

Back

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

Front

What is Newton's Second Law of Motion?

Back

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 (F = m * a).

Front

How does mass affect acceleration when the same force is applied?

Back

According to Newton's Second Law, if the same force is applied, an object with less mass will experience greater acceleration than an object with more mass.

Front

What is the relationship between action and reaction forces?

Back

According to Newton's Third Law, for every action, there is an equal and opposite reaction. This means that forces always occur in pairs.

Front

What is the net force acting on an object?

Back

The net force is the vector sum of all the forces acting on an object. It determines the object's acceleration.

Front

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

Back

To calculate the net force, subtract the smaller force from the larger force and apply the direction of the larger force.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to the mass of the object.

Front

What is the significance of the coefficient of friction in motion?

Back

The coefficient of friction determines the amount of frictional force between two surfaces in contact, affecting the motion of objects.

Front

How does a change in velocity relate to acceleration?

Back

Acceleration is defined as the rate of change of velocity over time. If an object's velocity changes, it is experiencing acceleration.

Front

What is the effect of balanced forces on an object's motion?

Back

Balanced forces result in a net force of zero, meaning the object will remain at rest or continue moving at a constant velocity.
