Forces practice test questions

Front

What is a free body diagram?

Back

A graphical representation used to visualize the forces acting on an object.

Front

What does the normal force depend on?

Back

The normal force depends on the weight of the object and the angle of the surface it is on.

Front

What are the two main classifications of forces?

Back

Contact forces and field forces.

Front

What happens to an object when unbalanced forces act on it?

Back

The object will accelerate in the direction of the larger force.

Front

What is friction?

Back

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

Front

How does the coefficient of friction affect motion?

Back

A lower coefficient of friction results in greater acceleration for an object.

Front

What is gravitational force?

Back

The force of attraction between two masses, such as the Earth and an object.

Front

What is the relationship between mass and acceleration?

Back

According to Newton's second law, acceleration is inversely proportional to mass when force is constant.

Front

What is the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a).

Front

What is the effect of surface type on friction?

Back

Different surfaces have different coefficients of friction, affecting the frictional force.
