P.5F - Forces and Motion Review

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. (F = ma)

Front

How do you calculate net force?

Back

Net force is calculated by subtracting opposing forces from the applied force. (Net Force = Applied Force - Frictional Force)

Front

What is a free body diagram?

Back

A diagram that shows all the forces acting on an object, represented by arrows.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) is calculated using the formula: a = F/m, where F is the net force and m is the mass.

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force is the Newton (N).

Front

What does it mean for an object to be in equilibrium?

Back

An object is in equilibrium when the net force acting on it is zero, resulting in no acceleration.

Front

How do you determine the tension in a rope holding an object at rest?

Back

The tension in the rope equals the weight of the object if it is in equilibrium. (Tension = Weight = mg)

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 the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, calculated as Weight = mass × gravitational acceleration (W = mg).

Front

What is the effect of increasing mass on acceleration if the net force is constant?

Back

If the net force is constant, increasing mass will result in a decrease in acceleration.
