Physics Review DA 2

Front

What is net force?

Back

Net force is the total force acting on an object when all the individual forces are combined. It determines the object's acceleration.

Front

What happens when forces are balanced?

Back

When forces are balanced, the net force is zero, and the object remains at rest or continues to move at a constant speed.

Front

What happens when forces are unbalanced?

Back

When forces are unbalanced, the net force is not zero, causing the object to accelerate in the direction of the greater force.

Front

What is the formula for calculating force?

Back

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

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be caused by a change in speed or direction.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, acting parallel to the surfaces in contact.

Front

What is the effect of friction on motion?

Back

Friction can slow down or stop the motion of an object, depending on the surfaces in contact and the force applied.

Front

What does a constant speed graph look like?

Back

A constant speed graph is a straight line with a positive slope, indicating uniform motion.

Front

What does a negative acceleration graph look like?

Back

A negative acceleration graph slopes downward, indicating that the object is slowing down.

Front

What is the relationship between mass and acceleration?

Back

According to Newton's second law, for a given force, an increase in mass results in a decrease in acceleration.
