Acceleration and Projectile Motion

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time. It can be positive (speeding up) or negative (slowing down).

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) = Change in velocity (Δv) / Change in time (Δt).

Front

What does a negative acceleration indicate?

Back

Negative acceleration indicates that an object is slowing down or decelerating.

Front

What is projectile motion?

Back

Projectile motion is the motion of an object thrown into the air, subject to the force of gravity, following a curved path.

Front

What are the two components of projectile motion?

Back

The two components are horizontal motion (constant velocity) and vertical motion (accelerated motion due to gravity).

Front

How do you calculate the horizontal distance traveled by a projectile?

Back

Horizontal distance (x) = horizontal velocity (vx) × time (t).

Front

What is the effect of gravity on a projectile's vertical motion?

Back

Gravity causes the vertical velocity of a projectile to change over time, resulting in a parabolic trajectory.

Front

What is the significance of the initial vertical velocity (viy) in projectile motion?

Back

The initial vertical velocity (viy) determines how high the projectile will rise and how long it will stay in the air.

Front

How do you find the maximum height of a projectile?

Back

Maximum height (h) can be found using the formula: h = (viy^2) / (2g), where g is the acceleration due to gravity.

Front

What is the relationship between velocity and displacement?

Back

Velocity is the rate of change of displacement with respect to time.
