Suppose an impulse is applied to an object. What can you assume?
If an impulse is applied to an object, it can assumed that there will be a change in the object's momentum. This change in momentum will depend on the magnitude and direction of the impulse applied.
As a moving object's velocity decreases does its momentum decreases?
Yes, if a moving object's velocity decreases, its momentum will also decrease as momentum is directly proportional to velocity. Momentum is calculated as mass multiplied by velocity, so any change in velocity will result in a change in momentum in the same direction.
The change in an object velocity?
The change in an object's velocity is determined by its acceleration. If the object's acceleration is positive, its velocity increases; if it is negative, the velocity decreases. The larger the acceleration, the quicker the change in velocity will be.
What happens to the kinetic energy of the object?
The kinetic energy of an object increases as its speed increases, and decreases as its speed decreases. Kinetic energy is directly proportional to the square of the object's speed, meaning a small change in speed can have a significant impact on its kinetic energy.
What happens to the thermal energy of an object as temperature decreases as it increases?
As the temperature of an object decreases, its thermal energy also decreases because the particles within the object have less kinetic energy. Conversely, as the temperature increases, the thermal energy of the object increases as the particles move more rapidly, resulting in higher kinetic energy.
When the mass of an object increases how does the object's acceleration change?
As mass increases acceleration decreases.
What form of energy is related to change in speed?
Kinetic energy is related to the change in speed of an object. As an object's speed increases, its kinetic energy also increases, and as its speed decreases, its kinetic energy decreases.

The change in an object velocity?
The change in an object's velocity is determined by its acceleration. If the object's acceleration is positive, its velocity increases; if it is negative, the velocity decreases. The larger the acceleration, the quicker the change in velocity will be.
If all forces are equal and opposite how does anything accelerate?
If all forces are balanced, an object will not accelerate and will remain at a constant velocity. Acceleration occurs when there is an unbalanced force acting on an object, causing a change in its velocity.
What happens to gravitational force when there is change in mass?
It decreases. For the greater the mass of the object, the more gravity is has.
What happens to the kinetic energy of the object?
The kinetic energy of an object increases as its speed increases, and decreases as its speed decreases. Kinetic energy is directly proportional to the square of the object's speed, meaning a small change in speed can have a significant impact on its kinetic energy.
If an objects mass on earth is 4.2 what is its mass on the moon?
An object's mass remains the same regardless of where it is in the universe. So, if an object has a mass of 4.2 on Earth, it will also have a mass of 4.2 on the moon. However, the weight of the object would be different on the moon due to the moon's lower gravity compared to Earth.
What happens to the thermal energy of an object as temperature decreases as it increases?
As the temperature of an object decreases, its thermal energy also decreases because the particles within the object have less kinetic energy. Conversely, as the temperature increases, the thermal energy of the object increases as the particles move more rapidly, resulting in higher kinetic energy.
How does the motion of an object change when the force applied to it change?
When the force applied to an object changes, its motion can also change. If the force increases, the object's acceleration will increase, leading to a faster change in velocity. Conversely, if the force decreases, the object's acceleration will decrease, resulting in a slower change in velocity.
When heat flows from a hot object to a cold object the temperature of the cold object increases while the temperature of the hot object is what?
The temperature of the hot object decreases as it loses heat to the cold object. Heat always flows from a higher temperature object to a lower temperature object in an attempt to reach thermal equilibrium.
