Forces practice test questions

Front

What factors affect the amount of normal force on an object?

Back

The normal force is affected by the weight of the object and the types of surfaces in contact.

Front

What is the relationship between the coefficient of friction and acceleration?

Back

The lower the coefficient of friction, the greater the acceleration of an object on a surface.

Front

What does a free body diagram represent?

Back

A free body diagram shows all the forces acting on an object, helping to analyze its motion.

Front

How does gravitational force change with mass?

Back

As mass decreases, gravitational force also decreases.

Front

What is the effect of pulling up on an object while pushing it?

Back

Pulling up decreases the normal force, which reduces friction and makes it easier to move the object.

Front

Define gravitational force.

Back

Gravitational force is the attraction between two masses, dependent on their masses and the distance between them.

Front

What is friction?

Back

Friction is the force that opposes the motion of an object in contact with a surface.

Front

Explain the concept of net force.

Back

Net force is the total force acting on an object, calculated by combining all individual forces.

Front

What is the formula for calculating weight?

Back

Weight (W) = mass (m) × gravitational acceleration (g).

Front

What happens to acceleration if mass increases while the net force remains constant?

Back

If mass increases and net force remains constant, acceleration decreases.
