Acceleration, F=MA & Speed Flashcard (Gen-Ed) - End of 1.2 Exam

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can occur when an object speeds up, slows down, or changes direction.

Front

True or False: Acceleration only occurs when an object speeds up.

Back

False, acceleration occurs when an object speeds up, slows down, or changes direction.

Front

How do you calculate acceleration?

Back

Acceleration (a) can be calculated using the formula: a = F/m, where F is the net force applied to the object and m is its mass.

Front

Calculate the acceleration of a 150 kg object that is moved with a force of 300N.

Back

2 m/s²

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What are balanced forces?

Back

Balanced forces are two equal forces acting in opposite directions on an object, resulting in no change in motion.

Front

What is an example of velocity?

Back

35 mph EAST is an example of velocity because it includes both speed and direction.

Front

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

Back

When unbalanced forces act on an object, it will accelerate in the direction of the net force.

Front

What is the formula for force?

Back

The formula for force is F = m * a, where F is force, m is mass, and a is acceleration.

Front

What is the unit of acceleration?

Back

The unit of acceleration is meters per second squared (m/s²).
