S8P3 Review

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It is a vector quantity, meaning it has both magnitude and direction.

Front

How does mass affect acceleration?

Back

According to Newton's second law, acceleration is inversely proportional to mass when the same force is applied. A larger mass results in less acceleration.

Front

What is net force?

Back

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

Front

What does it mean for forces to be balanced?

Back

Balanced forces occur when two forces acting on an object are equal in size but opposite in direction, resulting in no net force and no change in motion.

Front

What does it mean for forces to be unbalanced?

Back

Unbalanced forces occur when the forces acting on an object are not equal, resulting in a net force that causes the object to accelerate in the direction of the greater force.

Front

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

Back

According to Newton's second law (F=ma), the force acting on an object is equal to the mass of the object multiplied by its acceleration.

Front

What is the effect of gravity on objects?

Back

Gravity is a force that pulls objects toward the center of the Earth. It affects the weight of an object and can influence its motion.

Front

How do you determine the direction of acceleration?

Back

The direction of acceleration is determined by the direction of the net force acting on the object. It will accelerate in the direction of the net force.

Front

What is the formula for calculating net force?

Back

Net force can be calculated by subtracting opposing forces from each other: Net Force = Force1 - Force2.

Front

What happens to an object at rest when unbalanced forces act on it?

Back

An object at rest will start to move in the direction of the net force when unbalanced forces act on it.
