Physics Semseter 1 Review

Front

Describe the object's movement when it has increasing velocity in the positive direction.

Back

The object is accelerating in the positive direction, meaning its speed is increasing as it moves forward.

Front

What is the formula to calculate acceleration when a force is applied?

Back

Acceleration (a) = Force (F) / Mass (m).

Front

If a 60 N force is applied to a 20 Kg cart, what is the acceleration?

Back

3 m/s².

Front

Describe the motion of an object that has constant velocity and then accelerates in the positive direction.

Back

The object moves at a steady speed for a period and then begins to speed up in the forward direction.

Front

What determines which cart will accelerate the fastest when the same force is applied?

Back

The mass of the cart; the lighter the cart, the greater the acceleration.

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

If you push against a wall with a force of 300 N, what force does the wall exert on you?

Back

300 N, as per Newton's Third Law.

Front

What is the relationship between mass and acceleration when a constant force is applied?

Back

Acceleration is inversely proportional to mass; as mass increases, acceleration decreases.

Front

Define increasing velocity in the context of motion.

Back

Increasing velocity means that the speed of the object is getting faster over time.

Front

What happens to an object's motion if it experiences a net force of zero?

Back

The object will either remain at rest or continue to move at a constant velocity.
