Forces Exam

Front

What is the normal force acting on an object resting on a surface?

Back

The normal force is the upward force exerted by a surface that supports the weight of an object resting on it.

Front

What does it mean for forces to be in equilibrium?

Back

Equilibrium occurs when all the forces acting on an object are balanced, resulting in a net force of zero.

Front

State Newton's First Law of Motion.

Back

An object at rest stays at rest, and an object in motion stays in motion at a constant velocity unless acted upon by a net external force.

Front

How do you calculate mass using force and acceleration?

Back

Mass can be calculated using the formula: Mass = Force / Acceleration.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to accelerate, as it results in a net force acting on the object.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's Second Law, Force = Mass x Acceleration.

Front

What is friction?

Back

Friction is the force that opposes the motion of an object when it is in contact with another surface.

Front

What is gravitational force?

Back

Gravitational force is the attractive force between two masses, such as the Earth and an object.

Front

What is the formula for calculating weight?

Back

Weight can be calculated using the formula: Weight = Mass x Gravitational Acceleration (W = mg).

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.
