What is projectile motion?

Back

Projectile motion is the motion of an object that is thrown into the air and is subject to the force of gravity. It follows a curved path called a parabola.

Front

What is the horizontal acceleration of a projectile?

Back

0 m/s². In projectile motion, there is no horizontal acceleration if air resistance is negligible.

Front

What is the vertical acceleration of a projectile?

Back

9.8 m/s². This is the acceleration due to gravity acting on the projectile.

Front

What happens to the speed of a projectile at its highest point?

Back

The vertical component of the speed is zero at the highest point, but the horizontal component remains constant.

Front

How does the speed of a projectile compare at different heights?

Back

For points at the same height, the speed is the same due to conservation of energy.

Front

What is the formula for the vertical displacement of a projectile?

Back

The formula is: y = v₀t + (1/2)gt², where y is the vertical displacement, v₀ is the initial vertical velocity, g is the acceleration due to gravity, and t is time.

Front

If a ball is thrown straight up, how long does it take to return to the original position?

Back

It takes the same amount of time to return as it took to reach the highest point.

Front

What is the effect of air resistance on projectile motion?

Back

Air resistance reduces the range and height of the projectile compared to ideal conditions without air resistance.

Front

What is the maximum height of a projectile?

Back

The maximum height is reached when the vertical velocity becomes zero.

Front

How do you calculate the time of flight for a projectile?

Back

The time of flight can be calculated using the formula: T = (2v₀sin(θ))/g, where v₀ is the initial velocity, θ is the launch angle, and g is the acceleration due to gravity.
