Forces and Motion

Front

What is the net force?

Back

The net force is the overall force acting on an object when all the individual forces are combined. It determines the object's motion.

Front

What is the unit to MEASURE force?

Back

The unit to measure force is the Newton (N).

Front

If an object is not moving, the forces acting upon it are _____________

Back

balanced. Balanced forces mean that the object is in a state of equilibrium.

Front

If two teams are pulling with the same amount of force, what will happen?

Back

They will not move at all. This is because the forces are balanced.

Front

What is the formula for calculating net force?

Back

Net Force = Force applied - Force opposing.

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 mass.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, measured in kilograms, while weight is the force exerted by gravity on that mass, measured in Newtons.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It is measured in meters per second squared (m/s²).

Front

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

Back

According to Newton's second law, Force = Mass x Acceleration (F = ma).

Front

What is friction?

Back

Friction is a force that opposes the motion of an object. It occurs when two surfaces come into contact.
