All Flashcards
What are the differences between scalar and vector quantities?
Scalar: Magnitude only (e.g., speed, mass, distance). Vector: Magnitude and direction (e.g., velocity, force, displacement).
What is the effect of gravity on an object in free fall?
The object accelerates downwards at approximately 9.8 m/s².
What is the effect of launching a projectile at an angle?
The projectile follows a curved path due to the combination of horizontal and vertical motion.
What happens when the slope of a position-time graph increases?
The velocity of the object increases.
What happens when the area under a velocity-time graph is positive?
The displacement of the object is in the positive direction.
What happens when an object is in free fall?
The object accelerates downwards at a constant rate (g = 9.8 m/s²).
What is the effect of gravity on an object in free fall?
The object accelerates downwards at approximately 9.8 m/s².
What happens when a projectile is launched at an angle?
The initial velocity has both horizontal and vertical components, affecting the range and maximum height.
What is the effect of increasing the launch angle (below 45 degrees) on the range of a projectile?
The range increases.
